statements contained in this Annual Report that are not purely historical are forward-looking statements within the meaning of Section 27A of
the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the
Exchange Act. Forward-looking statements are often identified by the use of words such as, but not limited to, "aim," “anticipate,” “believe,”
“could,”  “estimate,”  “expect,”  “intend,”  “may,”  “plan,”  “potential,”  “predict,”  “project,”  "seek,"  “should,”  “will,”  “would”  or  the  negative  of  those
terms,  and  similar  expressions  that  convey  uncertainty  of  future  events  or  outcomes  to  identify  these  forward-looking  statements.  Any
statements contained herein that are not statements of historical facts may be deemed to be forward-looking statements. Forward-looking
statements in this Annual Report include, but are not limited to, statements about:

our expectations related to the Agreement and Plan of Merger, dated as of February 25, 2024, or the Merger Agreement, among the
Company, Atlas Neon Parent, Inc., a Delaware corporation, or Parent, and Atlas Neon Merger Sub, Inc., a Delaware corporation and
a  wholly-owned  subsidiary  of  Parent,  or  Merger  Sub,  including  with  respect  to  the  parties’  ability  to  satisfy  the  conditions  to  the
consummation of the tender offer and the other conditions set forth in the Merger Agreement, statements about the expected timeline
for completing the transactions contemplated by the Merger Agreement, the Company’s and Parent’s beliefs and expectations and
statements  about  the  benefits  sought  to  be  achieved  by  Parent’s  proposed  acquisition  of  the  Company  and  the  possibility  of  any
termination of the Merger Agreement;

the success, cost and timing of our product development activities and clinical trials and the initiation of, enrollment in, availability of
data for and other events related to such clinical trials;

our belief that NGM707 has the potential to reprogram immunoglobulin-like transcript 4-, or ILT4-, and immunoglobulin-like transcript
2-, or ILT2-, expressing myeloid cells to shift them from a suppressive state that restricts anti-tumor immunity to a stimulatory state
that may promote anti-tumor immunity;

our ability to design and conduct a potential registrational trial of aldafermin in primary sclerosing cholangitis, or PSC, and our belief

the  therapeutic  potential  of  our  programs  (including  our  NGM438,  NGM831,  NGM621  and  NGM313  programs)  whose  further
development  is  dependent  on  our  ability  to  secure  potential  future  collaboration,  out  licensing,  partnering  or  other  business
development  arrangements,  or  BD  Arrangements,  with  third-party  partners  and  our  ability  to  secure  such  BD  Arrangements  on
beneficial terms, if at all, and, in the absence of such BD Arrangements, whether due to limitations imposed on our ability to secure
such BD Arrangements during the pendency of the Merger Agreement or otherwise, we are unlikely to advance development of such
product candidates unless our portfolio prioritization changes and we are able to secure the additional capital necessary to fund such
development;

our ability to obtain funding for our operations;

our  ability  to  maintain  compliance  with  the  listing  standards  of  The  Nasdaq  Stock  Market  LLC,  or  Nasdaq,  if  the  transactions
contemplated by the Merger Agreement are not consummated;

our estimates regarding future expenses, revenue, capital requirements and needs for additional funds;

RISK FACTOR SUMMARY

Below is a summary of material factors that make an investment in our common stock speculative or risky. Importantly, this summary
does not address all of the risks and uncertainties that we face. Additional discussion of the risks and uncertainties summarized in this risk
factor summary, as well as other risks and uncertainties that we face, can be found under “Risk Factors” in Part I, Item 1A of this Annual
Report. The below summary is qualified in its entirety by that more complete discussion of such risks and uncertainties. You should carefully
consider the risks and uncertainties described under “Risk Factors” in Part I, Item 1A of this Annual Report as part of your evaluation of an
investment in our common stock.

On  February  25,  2024,  we  entered  into  the  Merger  Agreement  with  Parent  and  Merger  Sub.  The  Merger  Agreement  provides  for,
among other things, (i) the acquisition of the Company by Parent through a cash tender offer, or the Offer, by Merger Sub for each issued
and outstanding share of our common stock, and (ii) the merger of Merger Sub with and into the Company, or the Merger, with the Company
surviving  the  Merger.  If  the  Merger  is  effected,  our  common  stock  will  be  delisted  from  The  Nasdaq  Global  Select  Market  and  we  will  be
privately held. During the pendency of the Merger, we may be subject to certain risks and uncertainties as more fully described under “Risk
Factors” in Part I, Item 1A of this Annual Report. If the Merger is not consummated for any reason, we will remain subject to the other risks
and uncertainties described herein.

Risks Related to the Merger

•

•

•

The consummation of the Offer and the Merger are subject to a number of conditions beyond our control, and if one or more of such
conditions  are  not  satisfied,  and  as  a  result,  we  do  not  complete  the  Offer  and  the  Merger,  we  would  remain  liable  for  significant
transaction  costs,  and  the  focus  of  our  management  would  have  been  diverted  from  advancing  our  three  key  development
opportunities, in each case without realizing any benefits of the Offer and the Merger.

Failure to complete the Offer and the Merger within the expected time frame, or at all, could have a material adverse effect on our
business, operating results, financial condition and our stock price.

The  Merger  Agreement  contains  provisions  that  could  discourage  a  potential  competing  acquirer  that  might  have  an  interest  in
acquiring all or a significant portion of our common stock from considering or proposing that acquisition, even if it were prepared to
pay consideration with a higher per share cash or market value than the Offer Price (as defined in the Merger Agreement).

• While the Offer and the Merger are pending, we are subject to uncertainties that could disrupt our business, and our stock price may
fluctuate significantly based on announcements regarding the Offer and the Merger or based on market perceptions of the likelihood
of the satisfaction of the conditions to the consummation of the Offer and the Merger outside of our control.

• While the Offer and the Merger are pending, we are subject to contractual restrictions that limit our ability to pursue or prevent us
from  pursuing  attractive  business  or  fundraising  opportunities  (if  any),  such  as  our  ability  to  raise  additional  capital,  incur
indebtedness or pursue BD Arrangements. In addition, if the Merger is not consummated, we may face increased difficulties raising
capital and may need to significantly delay,

4

Table of Contents

scale  back  or  discontinue  development  of,  or  abandon  some  or  all  of,  our  product  candidates,  or  scale  back  or  discontinue  our
discovery research efforts.

•

Stockholder  litigation  or  class  actions  lawsuits  could  prevent  or  delay  the  consummation  of  the  Offer  and  the  Merger,  divert
management’s  attention,  adversely  affect  our  ability  to  consummate  the  Merger  or  otherwise  negatively  impact  our  business,
operating results and financial condition.

• We  have  incurred,  and  will  continue  to  incur,  significant  costs  and  expenses,  including  fees  for  professional  services  and  other

transaction costs, in connection with the Offer and the Merger.

Other Risks Related to Our Business

• We  have  incurred  net  losses  every  year  since  our  inception,  we  have  no  meaningful  source  of  revenue,  we  expect  to  continue  to

incur significant operating losses and we may never become profitable.

• We have minimal committed external funding for our development efforts and will need to rely on our own financial resources and our

ability to raise additional capital in order to further our development efforts.

• We need significant additional capital to proceed with development and commercialization of our current and potential future product
candidates and to finance our other operations, and that additional capital may not be available to us on acceptable terms, or at all;
as  a  result,  we  may  need  to  significantly  delay,  scale  back  or  discontinue  development  of  or  abandon  some  or  all  of  our  product
candidates, or scale back or discontinue our discovery research efforts, or we may be required to cease operations altogether.

• We expect to depend in the future on BD Arrangements with third-party partners for the development and commercialization of some
or  all  of  our  product  candidates  and  for  revenue  and,  if  we  are  unable  to  secure  those  BD  Arrangements,  or  if  any  future  BD
Arrangements  are  not  successful,  we  may  not  be  able  to  capitalize  on  the  market  potential  of  our  product  candidates  or  continue
their development. BD Arrangements involve numerous risks, any of which could materially and adversely affect our business and
financial condition.

• While we may consider BD Arrangements to advance development of the product candidates that are within our three key
priorities for clinical development, we are seeking BD Arrangements with third-party partners to progress, in whole or in part,
the  development  of  one  or  more  of  our  other  programs  whose  further  development  is  dependent  on  our  ability  to  secure
potential future BD Arrangements, which include NGM438, NGM831, NGM621 and NGM313, and if we are unable to secure
BD Arrangements to support these programs, we are unlikely to be able to advance their development unless our portfolio
prioritization changes and we are able to secure additional capital necessary to fund such development. We may discontinue
or abandon any or all of our programs altogether, in which case we will not realize any return on our investments in those
programs.

• We  may  not  be  able  to  obtain  and  maintain  relationships  with  future  partners  that  are  necessary  to  develop,  manufacture  and

commercialize some or all of our product candidates.

• We  rely  completely  on  contract  manufacturers  for  the  manufacture  of  our  product  candidates  and  the  process  of
manufacturing, and conducting release testing for, our biologic product candidates is complex, highly regulated and subject
to many risks, any of which could substantially increase our costs and limit supply of our product candidates and any future
products needed for clinical trials and commercialization.

• We need to successfully complete rigorous preclinical and clinical testing of our product candidates before we can seek regulatory
approval.  The  regulatory  approval  processes  of  the  FDA  and  comparable  foreign  health  authorities  are  lengthy  and  inherently
unpredictable, and if we are not successful at each step of the process, commercialization of our product candidates will be delayed
or prevented.

• Our  product  candidates  are  in  early  stages  of  development,  with  our  most  advanced  product  candidates  only  in  Phase  2

development.

• Our product candidates may fail to demonstrate safety and efficacy in ongoing and future clinical trials, may never achieve
regulatory approval and, even if approved, may not be able to be successfully commercialized due to competition or other
factors.

• We may not successfully identify new product candidates to expand our development pipeline.

• Our  future  success  depends  in  part  on  our  ability  to  attract  and  retain  highly  skilled  employees,  including  members  of  our  senior

management team.

5

Table of Contents

• We  face  substantial  competition,  which  may  result  in  others  discovering,  developing  or  commercializing  products  before,  or  more

successfully than, us.

•

Even  if  we  obtain  approval  to  market  our  products,  these  products  may  become  subject  to  unfavorable  pricing  regulations,
reimbursement practices from third-party payors or healthcare reform initiatives in the United States and abroad, which could harm
our business.

• Our success depends in significant part upon our ability to obtain and maintain intellectual property protection for our products and

technologies.

• Our  principal  stockholders,  including  entities  affiliated  with  The  Column  Group,  Merck  and  our  management,  own  a  substantial

percentage of our stock and will be able to exert significant control over matters subject to stockholder approval.

• We or third parties we rely on or partner with could experience a cybersecurity incident that could harm our business.

• We are a “smaller reporting company” and the reduced disclosure requirements applicable to such companies that we have availed

ourselves of may make our common stock less attractive to investors.

•
The market price of our common stock has been and may continue to be volatile, and you could lose all or part of your investment.
• We continue to incur increased costs as a result of operating as a public company and our management devotes substantial time to
public company compliance initiatives; for example, we are obligated to develop and maintain proper and effective internal control
over financial reporting and to comply with the requirements of Section 404 of the Sarbanes-Oxley Act of 2002.

• We have failed in the past and may in the future fail to continue to meet the listing standards of Nasdaq, and as a result our common

stock may be delisted, which could have a material adverse effect on the liquidity of our common stock.

Item 1.    Business.

PART I

Overview of Our Business

We  are  a  biopharmaceutical  company  focused  on  discovering  and  developing  novel,  potentially  life-changing  medicines  based  on
scientific  understanding  of  key  biological  pathways.  Our  mission  is  to  translate  complex,  powerful  biology  with  rigor  and  urgency  into  life-
changing  medicines.  Our  strategy  is  built  on  a  straightforward  central  premise:  create  an  environment  that  both  allows  drug  discovery
research to thrive by focusing on powerful human biology unconstrained by therapeutic area or technology approach and remain grounded in
the singular motivation of delivering impactful medicines to address critical unmet or underserved needs of patients suffering from grievous
diseases. As explorers on the frontier of life-changing science, we aspire to operate one of the most productive research and development
engines in the biopharmaceutical industry. All therapeutic candidates in our pipeline have been generated by our in-house discovery engine,
led by biology and motivated by patient need.

Our biology-driven and therapeutic area agnostic discovery engine has produced a diverse pipeline of product candidates spanning
oncology,  liver  and  metabolic  disease  and  retinal  disease.  We  have  evolved  our  strategy  to  concentrate  our  resources  on  three  product
candidates  in  three  specific  disease  areas  and  to  continue  our  discovery  research  efforts.  For  our  other  product  candidates  and  potential
future opportunities that have been, and may in the future be, produced by our discovery engine, we are seeking collaboration, out licensing,
partnering or other business development arrangements, or BD Arrangements, with third-party partners with sufficient resources and relevant
domain expertise to further their development. We believe that this strategy, if successfully implemented, may enable more of the programs
in our pipeline to be advanced effectively and efficiently.

Pending Transactions Contemplated by the Merger Agreement

On February 25, 2024, we entered into the Agreement and Plan of Merger, dated as of February 25, 2024, or the Merger Agreement,
with  Atlas  Neon  Parent,  Inc.,  a  Delaware  corporation,  or  Parent,  and  Atlas  Neon  Merger  Sub,  Inc.,  a  Delaware  corporation  and  a  wholly-
owned subsidiary of Parent, or Merger Sub. Parent and Merger Sub are affiliates of The Column Group, LP, which, along with certain of its
affiliates,  is  collectively  referred  to  as  TCG.  TCG  is  our  largest  stockholder,  holding  approximately  26.7%  of  our  common  stock  as  of
December 28, 2023.

The Merger Agreement provides for, among other things, (i) the acquisition of the Company by Parent through a cash tender offer, or
the Offer, by Merger Sub for each issued and outstanding share of our common stock for $1.55 per share, or the Offer Price, and (ii) the
merger of Merger Sub with and into the Company, or the Merger, with the Company surviving the Merger. Subject to the terms of the Merger
Agreement, the Offer Price will be paid subject to any applicable tax withholding and without interest.

Upon the unanimous recommendation of the special committee of our board of directors, or the Special Committee, the members of
our board (other than David V. Goeddel, Ph.D. and Roger M. Perlmutter, M.D., Ph.D. who recused themselves because of their relationship
to  TCG,  and  William  J.  Rieflin,  who  recused  himself  because  he  had  entered  into  the  Rollover  Agreement  (as  defined  in  the  Merger
Agreement)  at  the  time  of  the  board's  determination)  have  unanimously  determined  that  the  terms  of  the  Offer,  the  Merger  and  the  other
transactions contemplated by the Merger Agreement are fair to and in the best interests of the Company and the Unaffiliated Stockholders
(as  defined  in  the  Merger  Agreement),  authorized  and  approved  the  execution,  delivery  and  performance  by  the  Company  of  the  Merger
Agreement  and,  subject  to  the  terms  and  conditions  of  the  Merger  Agreement,  the  consummation  by  the  Company  of  the  transactions
contemplated  by  the  Merger  Agreement,  declared  the  Merger  Agreement  and  the  transactions  contemplated  by  the  Merger  Agreement
advisable and recommended that the Unaffiliated Stockholders accept the Offer and tender their shares of common stock pursuant to the
Offer.

The Offer is being made subject to all terms and conditions set forth in the Offer to Purchase, dated March 8, 2024, or, as it may be
amended  or  supplemented  from  time  to  time,  the  Offer  to  Purchase,  and  in  the  related  Letter  of  Transmittal,  or  as  it  may  be  amended  or
supplemented from time to time, the Letter of Transmittal. The Offer to Purchase and the Letter of Transmittal constitute the Offer. The Offer
will expire at one minute after 11:59 p.m., Eastern time, on April 4, 2024, unless extended in accordance with the terms of the Offer and the
Merger Agreement and the applicable rules and regulations of the U.S. Securities and Exchange Commission, or the SEC.

Pursuant to the terms of the Merger Agreement, as of the effective time of the Merger, or the Effective Time, by virtue of the Merger

and without any action on the part of the holders, (i) each outstanding share of our common

7

Table of Contents

stock  (other  than  any  shares  of  common  stock  (a)  held  in  the  treasury  of  the  Company,  (b)  owned,  directly  or  indirectly  by  TCG,  Parent,
Merger Sub or any other subsidiary of Parent, or the Rollover Stockholders (as defined in the Merger Agreement) at the commencement of
the Offer, (c) irrevocably accepted for purchase in the Offer or (d) owned by any stockholders who are entitled to and who properly exercise
appraisal  rights  under  Delaware  law)  will  be  converted  into  the  right  to  receive  the  Offer  Price  without  interest,  less  any  applicable  tax
withholding; (ii) the vesting of each option to purchase shares of our common stock, or Company Stock Options, shall be accelerated and (A)
each Company Stock Option that has an exercise price per share that is less than the Offer Price, or an In-the-Money Option, that is then
outstanding  will  be  cancelled  and,  in  exchange  therefor,  the  holder  of  such  cancelled  In-the-Money  Option  will  be  entitled  to  receive  an
amount in cash, without any interest thereon and subject to applicable tax withholding, equal to the product of (x) the total number of shares
of our common stock underlying such In-the-Money Option as of immediately prior to the Effective Time multiplied by (y) the excess of the
Offer Price over the applicable exercise price per share of the common stock underlying such In-the-Money Option, and (B) each Company
Stock Option that is not an In-the-Money Option will be cancelled for no consideration; and (iii) each unvested restricted stock unit, or RSU,
of the Company that is then outstanding shall become immediately vested in full and cancelled, and, in exchange therefor, the holder of such
cancelled RSU will be entitled to receive an amount in cash without interest, less any applicable tax withholding, equal to the Offer Price.

Merger Sub’s obligation to accept shares of our common stock tendered in the Offer is subject to conditions, including: (i) that the
number of shares of common stock validly tendered and not validly withdrawn equals at least a majority of all shares of our common stock
then  owned  by  the  Unaffiliated  Stockholders  as  of  the  expiration  of  the  Offer;  (ii)  the  accuracy  of  our  representations  and  warranties
contained  in  the  Merger  Agreement  (subject  to  certain  exceptions  and  qualifications  described  in  the  Merger  Agreement  and  except,
generally,  for  any  inaccuracies  that  have  not  had  a  Company  Material  Adverse  Effect  (as  defined  in  the  Merger  Agreement));  (iii)  our
performance in all material respects of our obligations under the Merger Agreement and (iv) the other conditions set forth in Exhibit A to the
Merger Agreement. The obligations of Parent and Merger Sub to consummate the Offer and the Merger under the Merger Agreement are not
subject to a financing condition.

Following  the  completion  of  the  Offer,  subject  to  the  absence  of  injunctions  or  other  legal  restraints  preventing  or  prohibiting  the
consummation of the Merger, Merger Sub will merge with and into the Company, with the Company surviving as a wholly-owned subsidiary
of  Parent,  pursuant  to  the  procedure  provided  for  under  Section  251(h)  of  the  Delaware  General  Corporation  Law,  without  any  additional
stockholder approvals. The Merger will be effected as soon as practicable following the time at which Merger Sub purchases the shares of
common stock validly tendered and not withdrawn in the Offer.

The Merger Agreement contains customary representations and warranties by Parent, Merger Sub and the Company. The Merger
Agreement  also  contains  customary  covenants  and  agreements,  including  with  respect  to  the  operations  of  our  business  between  signing
and closing.

The Merger Agreement contains customary non-solicitation restrictions prohibiting our solicitation of alternative business combination
transactions and restricts our ability to furnish non-public information to, or participate in any discussions or negotiations with, any third party
with  respect  to  any  such  alternative  business  combination  transaction,  subject  to  customary  exceptions  in  the  event  of  an  acquisition
proposal  that  was  not  solicited  in  violation  of  these  restrictions  and  that  our  board  of  directors  (acting  upon  the  recommendation  of  the
Special  Committee)  or  the  Special  Committee  determines  constitutes  or  could  reasonably  be  expected  to  lead  to  a  Superior  Company
Proposal (as defined in the Merger Agreement).

The Merger Agreement contains customary termination rights for both Parent and Merger Sub, on the one hand, and the Company,
on  the  other  hand,  including,  among  others,  for  failure  to  consummate  the  Offer  on  or  before  June  15,  2024.  If  the  Merger  Agreement  is
terminated under certain circumstances specified in the Merger Agreement in connection with our entry into an agreement with respect to a
Superior Company Proposal, we will be required to pay Parent a termination fee of $2.0 million.

We anticipate that the Offer and the Merger contemplated under the Merger Agreement will be consummated in the second quarter
of 2024. However, there can be no assurance that the Offer and the Merger contemplated by the Merger Agreement will be completed. If the
Merger is effected, our common stock will be delisted from The Nasdaq Stock Market LLC and our obligation to file periodic reports under the
Securities Exchange Act of 1934, as amended, or the Exchange Act, will terminate, and the Company will be privately held.

Pending consummation of the Offer and the Merger, the Merger Agreement generally requires us to operate in the ordinary course of
business consistent with past practice and restricts us from taking certain actions with respect to our business and financial affairs without
Parent’s  consent.  Such  restrictions  will  be  in  place  until  either  the  Offer  and  the  Merger  are  consummated  or  the  Merger  Agreement  is
terminated. These restrictions could restrict

Table of Contents

our ability to pursue or prevent us from pursuing attractive business or fundraising opportunities (if any) that arise prior to the consummation
of the Offer and the Merger. For example, our ability to raise additional capital through the issuance of equity securities, incur indebtedness
or pursue BD Arrangements are generally restricted without Parent’s consent during the pendency of the Offer and the Merger. In addition, if
the  Merger  is  not  consummated,  we  may  face  increased  difficulties  raising  capital  and  may  need  to  significantly  delay,  scale  back  or
discontinue development of, or abandon some or all of, our product candidates, or scale back or discontinue our discovery research efforts.
See  "Risk  Factors  -  Risks  Related  to  the  Offer  and  the  Merger."  The  following  discussion  of  our  product  development  and  other  plans
assumes that the transactions contemplated by the Merger Agreement are not consummated and we continue to operate as a public stand-
alone entity. For further information, see Management’s Discussion and Analysis of Financial Condition and Results of Operations, included
in Item 7 of this Annual Report.

Clinical Development Focused on Three Key Priorities

Our Pipeline

We are currently prioritizing the majority of our execution efforts and significant resources on three key development opportunities:

•

•

•

completing  a  Phase  1  Part  1b  dose  escalation  cohort  of  the  ongoing  Phase  1/2  trial  evaluating  NGM707  in  combination  with
KEYTRUDA® (pembrolizumab) for the treatment of patients with advanced or metastatic solid tumors,

designing a potential registrational trial of aldafermin in primary sclerosing cholangitis, or PSC, and continuing discussions with the
United  States  Food  and  Drug  Administration,  or  FDA,  including  on  the  proposed  utilization  of  a  primary  endpoint  composed  of
surrogate biomarkers with the goal of obtaining accelerated approval from the FDA; and

producing  a  toxicology  package  that  we  hope  will  support  the  potential  initiation  of  a  Phase  2  proof-of-concept  trial  of  NGM120  in
patients with hyperemesis gravidarum, or HG.

Subject to our ability to obtain sufficient additional capital, whether through financing activities or potential future BD Arrangements,
we may in the future pursue development of other product candidates and programs. While we may consider BD Arrangements to advance
these three key priorities for clinical development, we intend to invest our resources in their development, contingent upon capital availability
as described below, in the absence of BD Arrangements.

FGF19 = fibroblast growth factor 19; ILT2 = immunoglobulin-like transcript 2; ILT3 = immunoglobulin-like transcript 3; ILT4 = immunoglobulin-
like  transcript  4;  GFRAL  =  glial  cell-derived  neurotrophic  factor  receptor  alpha-like;  LAIR1  =  leukocyte-associated  immunoglobulin-like
receptor 1; PD-1 = programmed cell death protein 1

NGM707: ILT2/ILT4 Dual Antagonist Antibody for the Potential Treatment of Solid Tumors, Including MSS CRC Patients

Cancer involving solid tumors is a leading cause of death globally and was responsible for an estimated over nine million deaths in
2020. There were an estimated almost 17 million newly diagnosed cancer cases around the world in 2020, excluding non-melanoma skin
cancer. By 2040, the number of new cancer cases globally per

9

Table of Contents

year  is  expected  to  rise  to  over  25  million  and  the  number  of  cancer-related  deaths  per  year  to  grow  to  nearly  15  million,  excluding  non-
melanoma skin cancer. Cancer was the second leading cause of death in the United States in 2020, causing over 500,000 deaths that year.

Over the past decade, advances in cancer immunotherapy have driven significant improvements in clinical outcomes, especially in
certain cancer types that are immunogenic, or capable of eliciting an immune response. In particular, T cell checkpoint inhibitors, including
immune checkpoint inhibitors targeting programmed cell death protein 1 and programmed cell death protein ligand 1, or PD-1 and PD-L1,
respectively,  are  designed  to  inhibit  immune  checkpoint  pathways.  When  "active”  these  pathways  act  as  “brakes”  on  anti-tumor  immune
responses,  enabling  tumors  to  evade  detection  and  destruction  by  the  immune  system.  T  cell  checkpoint  inhibitors  essentially  work  to
“release” the “brakes” by inactivating those pathways. However, the overall response rate to PD-1/PD-L1 inhibitors is typically only 20% to
30%  and  many  cancer  patients  who  initially  experience  a  complete  or  partial  response  using  T  cell  checkpoint  inhibitors  may  eventually
experience cancer progression.

Our cancer research is currently focused on an emerging area of immuno-oncology research known as myeloid checkpoint inhibition.
The  tumor  microenvironment,  or  TME,  is  composed  of  both  cancerous  and  non-malignant  cells.  There  is  an  abundance  of  myeloid  cells
present in the TME of many tumor types. While myeloid cells play a critical role in the immune system, in the tumor they can contribute to the
inhibition of anti-tumor immune responses using multiple mechanisms, including suboptimal T-cell priming, T-cell suppression and physical
exclusion  of  immune  cells  from  the  cancer  cells.  In  essence,  they  serve  as  myeloid  checkpoints,  keeping  the  “brakes  on”  and  enabling
tumors to evade the immune system and drive resistance to cancer therapies. Our focus is on promoting myeloid reprogramming - switching
myeloid cells in the TME from an immunosuppressive state to a stimulatory state that enhances anti-tumor immunity by releasing the “brake”
and  allowing  these  myeloid  cells  to  potentially  play  a  pivotal  role  in  anti-tumor  activity  by  acting  to  both  kill  cancer  cells  directly  as  well
through the recruitment and activation of tumor-directed T cells.

We have built a portfolio of three myeloid checkpoint inhibitor product candidates, NGM707, NGM831 and NGM438, targeting four
receptors  whose  elevated  expression  in  myeloid  cells  in  the  TME  has  been  associated  with  poor  patient  responses  to  T  cell  checkpoint
inhibitors. We discovered NGM707, NGM831 and NGM438 while receiving funding from Merck Sharp & Dohme LLC, or Merck, as part of our
research collaboration with them. NGM707, NGM831 and NGM438 are now wholly-owned programs and we have the sole right, at our sole
discretion, to independently research, develop and commercialize each of them, at our sole expense, subject to the payment to Merck of low
single-digit royalties on commercial sales of any resulting products. See “Licensing and Collaboration Arrangements—Merck Collaboration.”

NGM707, the lead asset and area of primary focus going forward in our myeloid reprogramming and checkpoint inhibition portfolio, is
a dual antagonist monoclonal antibody that is designed to improve patient immune responses to tumors by inhibiting both Immunoglobulin-
like transcript 2, or ILT2, and Immunoglobulin-like transcript 4, or ILT4, receptors. We believe NGM707 has the potential to reprogram ILT4-
and  ILT2-expressing  myeloid  cells  to  shift  them  from  a  suppressive  state  that  restricts  anti-tumor  immunity  to  a  stimulatory  state  that  may
promote  anti-tumor  immunity.  Blocking  ILT2  also  may  reverse  inhibition  of  ILT2-expressing  lymphoid  cells  to  further  stimulate  anti-tumor
immune responses.

Clinical Development of NGM707

We  are  conducting  an  open-label  Phase  1/2  clinical  trial  evaluating  NGM707  as  a  monotherapy  and  in  combination  with

pembrolizumab for the treatment of patients with advanced or metastatic solid tumors.

The ongoing Phase 1 Part 1b cohort evaluating NGM707 in combination with pembrolizumab was initiated in the second quarter of
2022. In January 2024, we released data from this cohort with a data cutoff date of November 6, 2023. As of the data cutoff date, we had
enrolled  46  heavily  pretreated  patients  across  multiple  indications.  The  combination  of  NGM707  and  pembrolizumab  was  found  to  be
generally well-tolerated at all four dose levels of NGM707. Treatment-related adverse events, or TRAEs, occurred in 41% of patients, with
Grade 3 and above TRAEs occurring in 4% of patients. A maximum tolerated dose was not reached and the maximum administered dose
was 1800 mg. Of 37 response-evaluable patients (those completing at least one on-treatment scan), across multiple indications there were
four  confirmed  partial  responses,  including  one  pathological  complete  response  and  12  patients  with  stable  disease,  representing  an  11%
overall response rate, or ORR, and a 43% disease control rate, or DCR. The pathological complete response patient had significant target
lesion  reduction  that  allowed  subsequent  surgical  resection  of  all  gross  residual  disease,  resulting  in  a  confirmed  pathological  complete
response with no detectable active tumor cells and no detectable circulating tumor DNA. Moreover, three of the four patients with confirmed
partial responses had active liver metastases at baseline that were fully or partially reduced. Of the eight response-evaluable patients with a
diagnosis of microsatellite stable colorectal cancer, or MSS CRC,

10

Table of Contents

there  were  two  confirmed  partial  responses  (including  the  one  pathological  complete  response)  and  two  patients  with  stable  disease,
representing a 25% ORR and a 50% DCR. In addition, preliminary evidence of myeloid reprogramming was seen in peripheral blood and in
tumor biopsies consistent with the putative mechanism of NGM707.

The  Phase  1  Part  1a  cohort  evaluating  NGM707  as  a  monotherapy  completed  enrollment  in  2023.  In  that  cohort,  NGM707
monotherapy  appeared  to  be  generally  well  tolerated  at  all  dose  levels.  TRAEs  occurred  in  46%  of  the  patients,  with  Grade  3  and  above
TRAEs occurring in 5% of patients. A maximum tolerated dose was not reached and the maximum administered dose was 1800 mg. As of
the  November  6,  2023  data  cutoff  date  in  the  monotherapy  cohort,  there  was  one  confirmed  partial  response  and  ten  patients  with  stable
disease out of 35 response-evaluable patients (those completing at least one on-treatment scan). Eight patients had reduced target lesion
size, including a maximum decrease in one patient of 71%. Preliminary evidence of myeloid reprogramming was seen in peripheral blood
and in tumor biopsies of patients receiving treatment in the monotherapy cohort consistent with the putative mechanism of NGM707.

Two Phase 2 expansion cohorts evaluating NGM707 in combination with pembrolizumab in specific tumor types were initiated in the

first quarter of 2023. We are no longer enrolling in the Phase 2 expansion cohorts.

Enrollment in the Phase 1b cohort is projected to be complete in the second quarter of 2024. We anticipate providing an update in
mid-2024  on  the  Phase  1  Part  1b  cohort  and  planned  next  steps  in  the  NGM707  program,  including  the  potential  of  initiating  additional
cohorts, which may include MSS CRC patients. Clinical development of NGM707 beyond completing the Phase 1 Part 1b cohort, including
initiating additional cohorts, will require us to obtain the additional capital necessary to conduct such development.

NGM707 Patent Portfolio

As of December 31, 2023, we owned one issued U.S. patent covering NGM707, and the product and related compositions of matter
and methods of use are disclosed and claimed in other patent applications pending in the United States and in multiple jurisdictions outside
of the United States. We expect that the current patent and any patent that may issue from any of the pending applications will not expire
before 2041, excluding any patent term adjustments and any patent term extensions.

NGM707 Competition

We believe NGM707 is the most advanced candidate currently in clinical development targeting both ILT2 and ILT4. Other clinical
stage programs targeting both ILT2 and ILT4 include ImmunOs Therapeutics AG, or ImmunOs', IOS-1002 and Adanate’s ADA-011, both of
which are in Phase 1 trials.

We are aware of nine other clinical-stage programs in development that target either ILT4 or ILT2. Seven of them are clinical stage
anti-ILT4 programs from Merck, Concentra Biosciences LLC (formerly Jounce Therapeutics, Inc.), or Concentra, Immune-Onc Therapeutics,
Inc., or Immune-Onc, Celldex Therapeutics, Inc., OncoResponse, Inc., Elpiscience Biopharmaceuticals USA, Inc. and Bristol-Myers Squibb.
Merck's investigational anti-ILT4 therapeutic candidate, MK-4830, is currently in several Phase 2 studies. In late 2023, Concentra completed
a Phase 1/2 study of its anti-ILT4 monoclonal antibody, JTX-8064. The others are in Phase 1 trials. We are aware of two clinical-stage anti-
ILT2  programs  in  development:  Biond  Biologics  Ltd.,  or  Biond,  has  an  antagonist  antibody  targeting  ILT2,  BND-22  (also  known  as
SAR444881),  which  has  been  licensed  by  Sanofi,  in  a  Phase  1/2  trial  and  Agenus  Inc.  has  an  antagonist  antibody  targeting  ILT2,
AGEN1571, in a Phase 1 trial.

We are aware of at least 20 preclinical-stage programs targeting ILT2, ILT4 or both ILT2 and ILT4.

Aldafermin: Engineered Analog of Human Hormone FGF19 for the Potential Treatment of PSC

Primary  sclerosing  cholangitis,  or  PSC,  is  a  rare  liver  disease  that  irreparably  damages  the  bile  ducts,  leading  to  bile  acid
dysregulation,  which,  ultimately,  results  in  serious  liver  damage.  PSC  is  characterized  by  inflammation  and  fibrosis  of  the  bile  ducts
(hardening or narrowing of the bile duct walls), which obstructs the flow of bile in the liver. In the short term, bile acids accumulate in the liver,
leading to cell damage, cirrhosis and recurrent cholangitis. Common symptoms include fatigue, pruritus (severe itching), jaundice, abdominal
pain, depression and enlarged liver. In the long term, the bile acid accumulation can lead to loss of liver function, end-stage liver disease and
cancer.

There  are  currently  no  FDA-  or  EU-approved  therapies  for  PSC.  Unfortunately,  the  consequences  of  PSC  are  severe  when  left
untreated.  Between  5-20%  of  PSC  patients  develop  cholangiocarcinoma,  the  cancer  of  the  bile  duct.  Moreover,  one  in  two  PSC  patients
require a liver transplant within 10-15 years from diagnosis. The only curative treatment is liver transplant; however, PSC recurs in up to 20%
of transplant cases.

We have spent more than a decade discovering and developing product candidates that target various forms of cardio-metabolic and
liver diseases, including PSC. Through our research, we have identified multiple hormonal pathways of interest and our product candidates,
including  aldafermin,  stem  from  novel  insights  we  have  made  in  the  regulation  of  bile  acid  synthesis  and  liver  function.  Aldafermin  is  an
engineered  analog  of  human  hormone  fibroblast  growth  factor  19,  or  FGF19,  that  is  administered  through  a  once-daily  subcutaneous
injection. Aldafermin is the first and only FGF19 analog in clinical development and is wholly-owned by us.

We have generated a broad collection of clinical data studying aldafermin in several indications that informed our decision to pursue
the  potential  further  clinical  development  of  aldafermin  as  a  treatment  for  PSC.  Indications  previously  studied  with  aldafermin  include,  in
addition  to  PSC,  primary  biliary  cholangitis,  or  PBC,  bile  acid  malabsorption,  or  BAM,  and  non-alcoholic  steatohepatitis,  or  NASH.  In
December 2023, we received orphan drug designation from the FDA for aldafermin for the treatment of PSC.

Over 800 patients across multiple indications have been treated with aldafermin, which has repeatedly demonstrated powerful bile
acid suppression in patients with PSC and NASH. As a result, we believe aldafermin may have the differentiated potential to directly address
the underlying pathology of PSC and be well-tolerated. Unlike NASH patients, PSC patients had no statistically elevated cholesterol following
daily  exposure  to  aldafermin.  We  are  continuing  discussions  with  the  FDA  on  the  design  of  a  potential  registrational  trial  of  aldafermin  in
PSC, including on the proposed utilization of a primary endpoint composed of surrogate biomarkers with the goal of obtaining accelerated
approval  from  the  FDA.  We  plan  to  continue  working  with  the  FDA  to  reach  agreement  on  a  trial  design,  with  the  goal  of  initiating  trial
enrollment  by  the  end  of  2024,  contingent  upon  reaching  agreement  with  the  FDA  on  a  trial  design  and  obtaining  the  additional  capital
necessary to conduct the potential registrational trial.

Clinical Development of Aldafermin

In  February  2018,  we  reported  data  from  a  randomized,  double-blind,  placebo-controlled  Phase  2  study  of  aldafermin  for  the
treatment of PSC. While this Phase 2 study did not meet its primary endpoint of a statistically significant reduction in alkaline phosphatase,
an  exploratory  biomarker  of  PSC  disease  progression,  from  baseline  to  week  12,  aldafermin  demonstrated  statistically  significant
improvements in biomarkers of hepatic injury and fibrosis, as well as statistically significant reductions in biomarkers of bile acid synthesis
and serum bile acids, consistent with past studies of aldafermin in other liver diseases. The Phase 2 study met the secondary endpoints and
was generally well tolerated in the study.

In May 2023, we announced positive results from the Phase 2b ALPINE 4 trial of aldafermin in patients with compensated cirrhosis
(liver fibrosis stage 4 or F4) due to NASH. ALPINE 4 met its primary endpoint, with aldafermin 3 mg demonstrating a statistically significant
reduction in Enhanced Liver Fibrosis, or ELF, score compared to placebo at 48 weeks of treatment. Although ALPINE 4 was not statistically
powered for the secondary endpoint of histological fibrosis improvement of ≥1-stage (NASH Clinical Research Network, or CRN, criteria), we
observed a dose-dependent trend in fibrosis improvement. In November 2023, we presented positive Phase 2b results from the ALPINE 4
trial of aldafermin in compensated cirrhosis (F4) due to NASH at AASLD The Liver Meeting.

Aldafermin Patent Portfolio

As  of  December  31,  2023,  we  owned  27  issued  patents  in  the  United  States,  as  well  as  issued  patents  in  more  than  40  foreign
countries, including various member states of the European Patent Office, or EPO, covering aldafermin, related compositions of matter and
methods  of  use.  We  also  own  patent  applications  covering  similar  subject  matter  in  the  United  States  and  multiple  foreign  jurisdictions
including Europe. We expect the earliest issued patents in the United States to expire in 2032, excluding any patent term adjustments and
any patent term extensions.

Aldafermin Competition in PSC

The  competitive  landscape  in  PSC  includes  investigational  drugs  at  various  stages  of  clinical  development.  Most  advanced  is  Dr.
Falk  Pharma’s  NorUDCA,  currently  in  Phase  3  trials  in  Europe.  We  are  aware  of  eleven  additional  programs  in  earlier  stage  trials,  from
companies including Hepagene Therapeutics, Inc., Cascade Pharmaceuticals, Inc. Orbsen Therapeutics Ltd., Chemomab Therapeutics Ltd.,
Curome Biosciences Co., Pliant Therapeutics, Inc., or Pliant, Escient Pharmaceuticals, or Escient, Galmed Pharmaceuticals Ltd., GENFIT
S.A., Mirum Pharmaceuticals, Inc., or Mirum, Ipsen S.A. and High Tide Therapeutics, Inc. Pliant has reported data from its Phase 2a clinical
trial  of  320  mg  of  integrin  antagonist  bexotegrast  in  PSC,  showing  positive  safety  and  preliminary  evidence  of  a  reduction  in  liver  fibrosis
markers  ELF  and  PRO-C3  relative  to  placebo  at  12  weeks.  Escient  and  Mirum  are  developing  assets  focused  on  PSC  patients  with
moderate-to-severe pruritus, and both are in Phase 2 trials.

NGM120: GFRAL Antagonist for the Potential Treatment of Hyperemesis Gravidarum

Our scientists have made several discoveries related to growth differentiation factor 15, or GDF15, including identifying its cognate
receptor glial cell-derived neurotrophic factor receptor alpha-like, or GFRAL. GFRAL is expressed in a specific region of the hindbrain and
remains  the  only  receptor  for  GDF15  identified  to  date.  We  have  developed  multiple  product  candidates  targeting  the  GFRAL/GDF15
pathway, including NGM120, a GFRAL antagonist antibody.

GDF15 is secreted from injured or stressed tissues and contributes to appetite reduction and body weight loss. GDF15 through the
GFRAL-expressing neurons, or GFRAL neurons, which are found exclusively in the area postrema and nucleus tractus solitarius of the brain
stem.  The  area  postrema,  located  outside  of  blood  brain  barrier,  is  a  well-known  chemoreceptor  trigger  zone  for  nausea  and  vomiting.
GDF15 dosing has been shown to trigger taste aversion (nausea-related behavior) in mice and vomiting in tree shrews. Moreover, in a Phase
1 study of NGM395, one of our GDF15 analog product candidates that we investigated as an obesity treatment, there was evidence of dose-
dependent  increase  in  frequency  and  severity  of  nausea/vomiting  in  healthy  volunteers,  further  suggesting  that  GDF15  plays  a  role  in
emesis.

Our  preclinical  research  also  suggests  the  central  role  of  the  GDF15/GFRAL  pathway  in  promoting  tumor-associated  appetite
suppression,  metabolic  regulation  and  immune  modulation.  In vivo  screening  of  human  genes  shows  that  GDF15  expression  leads  to  an
outsized effect on weight loss and, in animal models, elevated serum levels of GDF15 are a regulator of immune function, metabolism and
feeding.  In  addition,  elevated  serum  levels  of  GDF15  have  been  shown  to  be  associated  with  pregnancy,  beta  thalassemia,  prolonged
nutritional stress and deficits and other stressors.

Genetic and serological studies have linked GDF15/GFRAL to hyperemesis gravidarum, or HG. GDF15 levels have been shown to
increase steadily in the first 12 weeks of pregnancy and, on average, are higher in women who experience HG in pregnancy. Research has
further shown that women with GDF15 genetic variants associated with lower levels of GDF15 in a non-pregnant state are predisposed to
HG.

HG  is  a  severe  condition  that  affects  approximately  100,000  to  150,000  women  in  the  United  States  each  year.  Characterized  by
intractable nausea and vomiting during pregnancy, which results in dehydration, debility, weight loss and malnutrition, HG takes a significant
physical and psychosocial toll on patients. Consequently, HG can also lead to higher rates of fetal loss, preeclampsia, preterm birth, low birth
weight and malnutrition for the fetus. HG patients may experience symptoms requiring hospitalization throughout the entire pregnancy and
HG typically recurs in subsequent pregnancies. HG is the second leading cause of hospitalization in pregnancy (after preterm labor) and is
one of the costliest pregnancy complications to treat. There are currently no FDA-approved therapies for this condition.

NGM120 is an antagonist antibody that binds to GFRAL and is designed to block the effects of elevated serum levels of GDF15. We
designed  NGM120  as  a  potent,  humanized  monoclonal  antibody  inhibitor  of  GFRAL  with  the  potential  for  once-monthly  or  less  frequent
dosing. Preclinical studies suggest that NGM120 may prevent cisplatin-induced GDF15-mediated weight loss in rodents and reduce cisplatin-
induced  weight  loss  and  emesis  in  a  cynomolgus  monkey  model,  suggesting  that  targeting  GFRAL  has  the  potential  to  ameliorate  the
metabolic and emetic effects caused by overstimulation of GFRAL neurons by excessive GDF15.

We discovered NGM120 while receiving funding from Merck as part of our research collaboration. NGM120 is now a wholly-owned
program  and  we  have  the  sole  right,  at  our  sole  discretion,  to  independently  research,  develop  and  commercialize  NGM120,  at  our  sole
expense,  subject  to  the  payment  to  Merck  of  low  single-digit  royalties  on  commercial  sales  of  any  resulting  products.  See  “Licensing  and
Collaboration Arrangements—Merck Collaboration.”

Clinical Development of NGM120

We  have  previously  studied  NGM120  for  the  treatment  of  cancer  and  cancer-related  cachexia.  We  conducted  a  Phase  1  study  in
healthy subjects and are completing a Phase 1/2 clinical trial to assess NGM120’s effect on cancer and cancer-related cachexia in patients
with  select  advanced  solid  tumors,  metastatic  pancreatic  cancer  and  metastatic  castration-resistant  prostate  cancer.  To date, we have not
detected a clear signal of response to NGM120 in the Phase 1/2 trial, and we do not plan to develop NGM120 further in oncology. However,
given the compelling genetic and biological evidence supporting the hypothesis that GDF15 may play a direct role in HG, we are exploring
the potential initiation of a Phase 2 proof-of-concept study of NGM120 for the treatment of HG by the end of 2024. We are in the process of
producing a toxicology package to submit to regulatory authorities in Australia or the United Kingdom that we hope will support the potential
initiation of that trial. In our clinical studies of NGM120 for the treatment of cancer and cancer-related cachexia, NGM120 was found to be
generally well tolerated in the approximately 140 healthy volunteers and cancer patients that were treated.

NGM120 Patent Portfolio

As  of  December  31,  2023,  we  owned  two  issued  patents  in  the  United  States,  as  well  as  nine  issued  foreign  patents,  covering
NGM120 and related compositions of matter and methods of use. We also own pending patent applications covering similar subject matter in
the United States and multiple jurisdictions outside of the United States. We expect that the current patents and any patent that may issue
from any of the pending applications will not expire earlier than 2037, excluding any patent term adjustments and any patent term extensions.

NGM120 Competition

The  current  standard  of  care  for  nausea  and  vomiting  in  pregnancy  is  Diclegis,  a  combination  of  doxylamine  (antihistamine)  and
pyridoxine  (vitamin  B6),  which  was  approved  by  the  FDA  in  2013.  There  are  no  other  approved  therapies  for  HG  or  severe  nausea  and
vomiting in pregnancy, although several classes of therapies are used off-label: antiemetics (e.g., ondansetron, granisetron), antihistamines
(e.g., promethazine), gut motility stimulators (e.g., metoclopramide), steroids, antidepressants (e.g., mirtazapine) and anticonvulsants (e.g.,
gabapentin).

We  are  aware  of  two  publicly  disclosed  programs  targeting  GFRAL,  from  Cantius  Therapeutics,  LLC  and  CSPC  Pharmaceutical
Group  Limited,  both  of  which  are  in  preclinical  development.  There  are  three  clinical  stage  programs  we  are  aware  of  that  target  GDF15:
Pfizer’s ponsegromab is in Phase 2 trials in cancer cachexia and heart failure, CatalYm GmbH's, or CatalYm's, visugromab is in Phase 2
trials  in  multiple  solid  tumor  indications  and  Aveo  Oncology's,  or  Aveo's,  AV-380  is  in  a  Phase  1  trial  in  cancer  cachexia.  Kyinno
Biotechnology and Leap Therapeutics, Inc. have preclinical programs targeting GDF15.

Additional Programs Currently Without Meaningful Resource Allocation

Due to the need to conserve capital and prioritize focused execution, the remainder of our pipeline includes programs whose further
development is dependent on our ability to secure potential future BD Arrangements and, in the absence of such BD Arrangements, we are
unlikely  to  advance  development  of  these  product  candidates  unless  our  portfolio  prioritization  changes  and  we  are  able  to  secure  the
additional capital necessary to fund such development. As a result, we are seeking BD Arrangements with third-party partners possessing
sufficient resources and relevant domain expertise in the relevant therapeutic area in order to further clinical development of these programs.
These programs include:

• NGM438 and NGM831, currently being studied in a Phase 1/2 trial in combination with pembrolizumab and described in more detail

below.

• NGM621, a monoclonal antibody administered via intravitreal, or IVT, injection, which was engineered to potently bind to, and be a
long-acting  inhibitor  of,  complement  C3  with  the  treatment  goal  of  reducing  the  rate  of  disease  progression  in  patients  with
geographic atrophy, or GA, secondary to age-related macular degeneration, or AMD. Our Phase 2 clinical trial which evaluated the
efficacy and safety of NGM621 when given to patients with GA every four weeks or every eight weeks via IVT injections compared to
sham control did not meet its primary endpoint of a statistically significant reduction in the rate of change in GA lesion area growth
using slope analysis over 52 weeks of treatment with NGM621 versus sham.

• NGM313,  an  agonistic  antibody  that  selectively  activates  fibroblast  growth  factor  receptor  1c-beta-klotho,  or  FGFR1c/KLB,  which
regulates insulin sensitivity, blood glucose and liver fat and is administered every four weeks through a subcutaneous injection. In
2018, Merck licensed NGM313 and other FGFR1c/KLB agonists, but terminated its license rights in 2023 and returned the program
to us.

NGM438  is  an  antagonist  antibody  that  is  designed  to  inhibit  leukocyte-associated  immunoglobulin-like  receptor  1,  or  LAIR1,  and
thereby promote anti-tumor immune responses. NGM438 has the potential to potently block the binding of all collagens to LAIR1, including
tumor-derived collagens. Collagens produced by the tumor stroma, meaning the non-malignant, non-immune components of the tumor, are
believed to bind LAIR1 to create an immunosuppressive TME. The interaction of collagens from the tumor stroma with LAIR1 on immune
cells  represents  a  "stromal  checkpoint"  that  restrains  anti-tumor  immune  responses.  Reinvigoration  of  these  collagen-suppressed  immune
cells  by  blocking  the  binding  of  collagens  to  LAIR1  may  address  a  key  resistance  mechanism  that  limits  tumor  responses  to  current
immunotherapies.

NGM831 is an antagonist antibody that is designed to block the interaction of Immunoglobulin-like transcript 3, or ILT3 receptor, with
fibronectin,  as  well  as  other  cognate  ligands.  ILT3  is  a  fibronectin-binding  inhibitory  immune  receptor  that  receives  signals  from  the
extracellular matrix to directly promote myeloid cell suppression. ILT3 is expressed on a variety of immune cells including tumor-associated
myeloid cells, with particularly high expression on tolerogenic dendritic cells, or DCs, myeloid-derived suppressor cells and M2 macrophages.
High  ILT3  expression  is  associated  with  poor  survival.  Moreover,  fibronectin  has  been  shown  to  be  upregulated  in  multiple  cancers  and
associated  with  tumor  progression.  For  tumors  in  which  both  ILT3  and  fibronectin  are  upregulated,  the  ILT3-fibronectin  signaling  pathway
may  act  as  a  "stromal  checkpoint"  to  repress  myeloid  cell  function  and  inhibit  anti-tumor  immunity.  By  inhibiting  ILT3's  interaction  with
fibronectin and its other ligands, we believe NGM831 has the potential to mobilize a patient's own immune system to fight tumors by shifting
myeloid cells from a suppressive state to a stimulatory state and promoting anti-tumor activity.

In  2022,  we  initiated  an  open-label,  Phase  1/1b  clinical  trial  to  evaluate  NGM438  as  a  monotherapy  and  in  combination  with
pembrolizumab for the treatment of patients with advanced or metastatic solid tumors. Both the Phase 1 Part 1a cohort evaluating NGM438
as a monotherapy and the Phase 1 Part 1b cohort evaluating NGM438 in combination with pembrolizumab have completed enrollment. In
2022, we also initiated an open-label Phase 1/1b clinical trial to evaluate NGM831 as a monotherapy and in combination with pembrolizumab
for  the  treatment  of  patients  with  advanced  or  metastatic  solid  tumors.  Both  the  Phase  1  Part  1a  cohort  evaluating  NGM831  as  a
monotherapy and the Phase 1 Part 1b cohort evaluating NGM831 in combination with pembrolizumab have completed enrollment. In 2023,
we  initiated  an  open-label  Phase  1  Part  1c  dose  finding  cohort  of  that  trial  evaluating  the  triplet  combination  of  NGM831,  NGM438  and
pembrolizumab. This cohort is anticipated to complete enrollment in the first half of 2024.

As  of  December  31,  2023,  we  did  not  own  or  have  a  license  to  any  issued  patent  that  covers  NGM438.  However,  NGM438  and
related  compositions  of  matter  and  methods  of  use  are  disclosed  and  claimed  in  patent  applications  pending  in  the  United  States  and  in
multiple jurisdictions outside of the United States. Any patent that may issue from these applications or any related applications that we file is
expected to expire no earlier than 2041, excluding any patent term adjustments and any patent term extensions. As of December 31, 2023,
we owned one issued U.S. patent covering NGM831, and the product and related compositions of matter and methods of use are disclosed
and claimed in other patent applications pending in the United States and in multiple jurisdictions outside of the United States. The current
patent and any patent that may issue from any of the pending applications are expected to expire no earlier than 2040, excluding any patent
term adjustments and any patent term extensions.

We  are  aware  of  only  two  other  anti-LAIR1  antibodies  currently  in  Phase  1  clinical  development  by  Immune-Oncs  and  NextCure,
Inc., or NextCure, respectively. NextCure also has a Phase 1 product candidate in the clinic, a LAIR2 fusion protein designed to mimic the
natural decoy effects of LAIR2, which binds to collagens and blocks the activity of LAIR1. We are aware of only one other antibody being
pursued clinically for the treatment of solid tumors that is intended to block the interaction of Immunoglobulin-like transcript 3, or ILT3, with
fibronectin, as well as other cognate ligands, which is a Phase 1 asset of Immune-Onc. However, there are other programs that target ILT3
currently in clinical development by Immune-Onc and Carbiogene Therapeutics Co. Ltd., and five additional preclinical anti-ILT3 candidates
in development.

We have additional programs that are in various stages of development ranging from functional validation to preclinical development.
Given  the  breadth  of  opportunities  that  have  been,  and  may  in  the  future  be,  produced  by  our  discovery  engine,  we  are  also  seeking  BD
Arrangements with third-party partners to progress, in whole or in part, the development of one or more of our preclinical programs.

We do not own, and have no plans to establish, any manufacturing facilities. We currently use third-party contract development and
manufacturing organizations or contract manufacturing organizations, which we refer to collectively as CMOs, to manufacture and supply all
of the raw materials, drug substances and drug products for our

Manufacturing

15

Table of Contents

pipeline  programs,  including  all  the  materials  used  in  the  clinical  trials  of  our  product  candidates.  We  have  established  relationships  with
several CMOs, and the activities of our CMOs are overseen by an experienced group of employees and third-party consultants.

We  plan  to  continue  to  rely  on  CMOs  to  manufacture  commercial  quantities  of  any  products  for  which  we  successfully  obtain
regulatory approval, as well as to provide packaging, storage and distribution of any approved products. We have not entered into long-term
clinical  or  commercial  supply  agreements  with  any  of  our  CMOs.  In  addition,  each  of  our  product  candidates  relies  on  a  single  contract
manufacturer for supplies of its drug substance and drug product.

Competition

The  biopharmaceutical  industry  is  characterized  by  intense  competition  and  rapid  innovation.  Although  we  believe  that  we  hold  a
strong  position  in  research  in  certain  areas  of  cancer  and  liver  and  metabolic  diseases,  our  competitors  may  be  able  to  develop  other
compounds  or  drugs  that  are  able  to  achieve  similar  or  better  results.  Our  competitors  include  multinational  pharmaceutical  companies,
specialized biotechnology companies, universities and other research institutions. Smaller or earlier-stage companies also may prove to be
significant competitors, particularly through collaboration or partnering arrangements with large, established companies. We believe the key
competitive  factors  that  will  affect  the  development  and  commercial  success  of  our  product  candidates  are  their  efficacy,  safety  and
tolerability profile, and reliability.

There  are  many  pharmaceutical  companies,  biotechnology  companies,  public  and  private  universities  and  research  organizations
actively engaged in the research and development, or R&D, of products that may be competitive with our product candidates. A number of
pharmaceutical  companies,  including  AbbVie,  Amgen,  AstraZeneca,  Bayer,  Boehringer  Ingelheim,  Bristol-Myers  Squibb,  Eisai,  Eli  Lilly,
Gilead, GlaxoSmithKline, Ipsen, Johnson & Johnson, Merck, Novartis, Novo Nordisk, Organon, Pfizer, Roche, Sanofi and Takeda, as well as
large and small biotechnology companies such as 89Bio, Agenus, Akero, Alentis, AVEO (a LG Chem company), Biond, BriSTAR, Cantius,
Carbiogene,  Cascade  Pharmaceuticals,  CatalYm,  Celldex,  ChemomAb,  Concentra,  CSPC,  Curome  Biosciences,  CymaBay  Therapeutics,
Dr. Falk Pharma, Elpiscience, Escient, Galmed, Genfit, Hepagene, High Tide Therapeutics, Immune-Onc, ImmunOs Therapeutics, Inventiva,
Kyinno  Biotechnology,  Leap  Therapeutics,  Madrigal,  Mirum,  NextCure,  OncoResponse,  Orbsen  Therapeutics,  Pliant,  Salix,  Scholar  Rock
and Tizona, are pursuing the development or marketing of pharmaceuticals that target the same diseases that we are targeting. It is probable
that the number of companies seeking to develop products and therapies for the treatment of cancer and liver and metabolic diseases will
increase.

Many of these and other existing or potential competitors have substantially greater financial, technical, human and other resources
than we have and may be better equipped to develop, manufacture and market technologically superior products. In addition, many of these
competitors  have  significantly  greater  experience  than  we  have  in  undertaking  preclinical  studies  and  human  clinical  trials  of  new
pharmaceutical products and in obtaining regulatory approvals of human therapeutic products. Accordingly, our competitors may succeed in
obtaining  FDA  approval  for  superior  products  or  for  other  products  that  would  compete  with  our  product  candidates.  In  addition,  other
technologies or products may be developed that have an entirely different approach or means of accomplishing the intended purposes of our
products, which might render our technology and products noncompetitive or obsolete.

For  more  information  regarding  the  competition  that  our  key  product  candidates  face,  or  may  face,  see  the  discussion  of  specific

competition for each product candidate in “—Our Pipeline.”

Intellectual Property

Our intellectual property is critical to our business and our success depends, in part, on our ability to obtain and maintain intellectual
property protection for our product candidates, technology and know-how, to defend and enforce our intellectual property rights, in particular,
our patent rights, to preserve the confidentiality of our trade secrets and to operate without infringing the proprietary rights of others.

We seek to protect the proprietary technology that we believe is important to our business through a variety of methods, including
seeking  and  maintaining  patents  and  patent  applications  intended  to  cover  our  product  candidates,  their  compositions-of-matter,  their
methods of use and the processes for their manufacture and any other aspects of inventions that are commercially important to the success
of our business. We seek to obtain domestic and international patent protection and, in addition to filing and prosecuting patent applications
in the United States, we may file counterpart patent applications in additional countries where we believe such foreign filing is likely to be
beneficial.

16

Table of Contents

As of December 31, 2023, our patent portfolio includes over 600 patents and applications, including over 60 issued U.S. patents and
over  20  pending  U.S.  patent  applications  covering  our  product  candidates,  certain  aspects  of  our  proprietary  technology,  and  related
inventions  and  improvements.  Our  patent  portfolio  also  includes  over  500  patents  and  patent  applications  in  jurisdictions  outside  of  the
United States that, in many cases, are counterparts to our U.S. patents and patent applications. For more information regarding the patents
and  patent  applications  relating  to  certain  of  our  pipeline  programs,  see  the  discussion  of  intellectual  property  protection  for  each  such
product  candidate  in  “—Our  Pipeline.”  The  patent  landscape  surrounding  our  product  candidates  is  crowded,  and  we  do  not  know  if  our
pending patent applications will be issued with the claims we are seeking or if our issued patents will withstand challenges from third parties.

Not all patent applications result in the issuance of patents. Patent applications in the United States and certain other jurisdictions are
maintained in secrecy for 18 months or potentially longer, so public disclosure of discoveries via the publication of patent applications or in
the scientific literature is often delayed. As a result, we cannot be certain of the priority of inventions covered by our patent applications and
may be subject to claims of priority from third parties or the United States Patent and Trademark Office, or USPTO, against which we will
need to defend ourselves.

In addition, the scope of claims that may be allowed in any granted patent may be significantly reduced from the coverage claimed in
the initial patent application. Further, the scope of the claims in an issued patent may be reinterpreted and, in some cases, narrowed or even
cancelled after issuance by courts upon review. In addition, many jurisdictions allow third parties to challenge issued patents in administrative
proceedings that may result in further narrowing or cancellation of patent claims. As a result, even issued patents may not provide sufficient
protection from competitors.

When patents are issued, the term of each individual patent will depend on the legal term for patents in the countries in which it is
granted. In most countries, including the United States, the patent term is 20 years from the earliest claimed filing date of a non-provisional
patent  application  in  the  applicable  country.  The  actual  term  of  any  patent  that  may  issue  from  the  above-described  patent  applications
claiming  one  of  our  product  candidates  could  be  longer  than  described  above  due  to  patent  term  adjustment  or  patent  term  extension,  if
available, or shorter if we are required to file terminal disclaimers.

Any  changes  we  make  to  the  composition,  formulation,  method  of  delivery  or  other  attributes  of  our  current  and  future  product
candidates to cause them to have what we view as more advantageous properties may not be covered by our existing patents and patent
applications, and we may be required to file new applications and/or seek other forms of protection.

Even if patents are issued, if a third party engages in activities covered by valid claims of our patents, we may be required to engage
in enforcement actions in the courts to enforce our patents. Not all enforcement proceedings are successful. We also must take care not to
infringe  the  valid  patents  of  third  parties.  Third-party  patent  rights  that  purport  to  cover  our  product  candidates  or  their  discovery,  use  or
manufacture  may  require  us  to  challenge  their  validity  in  court  or  administrative  proceedings  and  prevail  in  such  challenges,  to  alter  our
development or commercial strategy or our product candidates or their uses and manufacture, to obtain licenses to such patents and/or to
stop  certain  activities  altogether.  We  hold  various  licenses  with  third  parties  to  their  intellectual  property,  including  those  with  Horizon
Discovery  Ltd.  and,  as  described  below,  Lonza  Sales  AG,  or  Lonza,  for  the  use  of  their  cell  lines.  The  patent  positions  of  biotechnology
companies  like  ours  are  generally  uncertain  and  involve  complex  legal,  scientific  and  factual  questions.  We  may  not  obtain  or  maintain
adequate patent protection for any of our programs and product candidates.

In  addition  to  patent  protection,  we  also  rely  on  trademark  registration,  trade  secrets,  know-how,  other  proprietary  information  and
continuing  scientific  innovation  to  develop  and  maintain  our  competitive  position.  We  seek  to  maintain  the  confidentiality  of  proprietary
information to protect aspects of our business that are not amenable to, or that we do not consider appropriate for, patent protection. As a
part of these efforts, it is our policy to require our employees, consultants, outside scientific collaborators, sponsored researchers and other
advisors to execute confidentiality agreements upon the commencement of their respective relationships with us. These agreements provide
that all confidential information concerning our business or financial affairs developed or made known to the individual during the course of
the  individual’s  relationship  with  us  is  to  be  kept  confidential  and  not  disclosed  to  third  parties  except  in  specific  circumstances.  Our
agreements  with  employees  also  provide  that  all  inventions  conceived  by  the  employee  in  the  course  of  employment  with  us  or  from  the
employee’s use of our confidential information are our exclusive property, even after they are no longer our employees. Although we take
these and other steps to safeguard our proprietary information and trade secrets, these agreements may be breached or third parties may
independently develop substantially equivalent proprietary information and techniques

17

Table of Contents

or otherwise gain access to our trade secrets or disclose our technology. Thus, we may not be able to meaningfully protect our proprietary
information that is not otherwise protected by patent.

See “Risk Factors—Risks Related to Our Intellectual Property” for information regarding the risks related to our intellectual property.

Licensing and Collaboration Arrangements

Merck Collaboration

In  2015,  we  entered  into  a  research  collaboration,  product  development  and  license  agreement  with  Merck,  which,  together  with
amendments  made  prior  to  June  30,  2021,  is  referred  to  as  the  Original  Collaboration  Agreement.  The  original  research  phase  of  the
collaboration was for five years and was extended by Merck for an additional two years through March 2022. On June 30, 2021, we entered
into  an  amended  and  restated  research  collaboration,  product  development  and  license  agreement  with  Merck,  or  the  Amended
Collaboration Agreement, replacing the Original Collaboration Agreement and extending the research phase of the collaboration, but with a
narrower scope than in the Original Collaboration Agreement. Under the Amended Collaboration Agreement, the research program term for
certain cardiovascular or metabolic-, or CVM-, related programs will continue through March 31, 2024, unless the parties mutually agree to
extend the research program term through March 31, 2026, in which case Merck would provide up to a total of $20.0 million in R&D funding
during the additional two years of the CVM research program term. We do not expect the research program term to be extended.

In 2023, the R&D funding we received from Merck under the Amended Collaboration Agreement was significantly less compared to
funding received in prior years. For the first half of 2024, we will receive minimal funding from Merck and we do not expect any funding at all
from  Merck  thereafter.  Although  new  CVM-related  programs  may  be  added  to  the  collaboration  if  recommended  by  us  and  selected  by
Merck, we do not expect any new CVM-related programs to be added.

During the three-month period before the end of the research program term for the CVM-related programs, Merck has the right to
review  the  product  candidates  from  each  applicable  program  and  to  elect  to  have  R&D  activities  continue  under  the  collaboration  for  an
additional  period,  referred  to  as  a  Tail  Period.  If  Merck  makes  such  an  election,  which  we  do  not  expect  it  to  do,  then  the  applicable  Tail
Period would begin at the end of the research program term for the applicable program and would end on the earlier of achievement of the
license option exercise point (as specified in the Amended Collaboration Agreement for each such candidate) or three years, except that in
certain circumstances a Tail Period may continue beyond three years if the license option exercise point has not been achieved by such time.
All R&D work on CVM-related programs during the applicable Tail Period, if any, would be conducted by Merck or its third-party contractors at
Merck’s expense.

Under the Amended Collaboration Agreement, Merck retains license options to obtain an exclusive, worldwide license, on specified
terms,  to  each  collaboration  compound  (and  its  related  compounds)  that  remains  within  the  scope  of  the  continuing  collaboration  for  the
CVM-related  programs.  Merck  generally  has  a  one-time  right  to  exercise  its  license  option  for  any  product  candidate  when  we  or  Merck
achieve the specified license option exercise point. Upon Merck’s exercise of a license option for any CVM-related program, which we do not
expect it to do, Merck would pay us an option exercise fee of $6.0 million and we would be eligible to receive a milestone payment of $10.0
million if Merck subsequently completes a proof-of-concept trial for a product candidate from such program.

If Merck exercises its license option to a product candidate and its related compounds, referred to as a Licensed Program, we would
have  the  option  to  receive  milestones  and  royalty  payments  or,  in  certain  cases,  prior  to  Merck  initiating  any  Phase  3  clinical  trial  of  such
licensed compound, to co-fund development and participate in a global cost and profit share arrangement of up to 50%, with an additional
option  to  co-detail  any  such  licensed  compound  in  the  United  States.  If  we  do  not  elect  to  exercise  our  cost  and  profit  share  option  for  a
particular  licensed  compound,  we  would  be  eligible  to  receive  an  aggregate  of  up  to  $469.0  million  in  milestone  payments  upon  the
achievement  of  specific  clinical  development  and  regulatory  events,  commercial  milestone  payments  of  up  to  $125.0  million  and  royalties
from low-double digit to mid-teen percentages of worldwide net sales of such licensed compound.

Merck would be responsible, at its own cost, for all development and commercialization of product candidates from each Licensed
Program,  subject  to  our  options  to  cost  and  profit  share  worldwide,  and  to  co-detail  those  compounds  in  the  United  States  as  described
above. If Merck does not exercise its license option with respect to a particular candidate and its related compounds within the applicable
time  period,  in  most  instances  we  retain  all  rights  to  research,  develop  and  commercialize  that  candidate  and  those  compounds  on  a
worldwide basis,

18

Table of Contents

either  alone  or  in  partnership  with  a  third  party,  subject  to  the  payment  to  Merck  of  low  single-digit  royalties  on  commercial  sales  of  any
resulting products.

Under  the  Amended  Collaboration  Agreement,  we  also  granted  Merck  a  worldwide,  exclusive  right  to  conduct  R&D  on,  and  to
manufacture, use and commercialize, small molecule compounds identified or developed by Merck that have specified activity against any
target that we are researching or developing under the research program term of the collaboration. Merck’s research license for its own small
molecule  program  will  become  non-exclusive  if  Merck  does  not  exercise  its  option  to  a  product  candidate  against  a  target  at  its  option
exercise  point,  but  Merck  will  retain  an  exclusive  license  to  any  small  molecule  compounds  that  it  has  already  identified  and  developed.
Merck has sole responsibility for R&D of any of these small molecule compounds, at its own cost. We are eligible to receive milestone and
royalty payments on small molecule compounds that are developed by Merck under such a license from us.

In addition to the options and exclusive licenses that we granted or are obligated to grant to Merck, we have the following exclusivity
obligations to Merck under the Amended Collaboration Agreement. During the applicable research program term and Tail Period, if any, for
the CVM-related programs, we may not directly or indirectly research, develop, manufacture or commercialize, outside of our collaboration
with Merck, any product with specified activity against any target that is being researched or developed under the applicable programs and, if
Merck  exercises  its  license  option  for  a  program,  we  may  not  directly  or  indirectly  research,  develop,  manufacture  or  commercialize  any
product with specified activity against the target that is the subject of that Licensed Program for so long as Merck’s license to it remains in
effect. In addition, we are prohibited from directly or indirectly researching, developing or commercializing any product for the treatment of
heart failure with preserved ejection fraction during the research program term for the CVM-related programs.

Pursuant to the Amended Collaboration Agreement, we have the right, in our sole discretion, to independently research, develop and
commercialize  the  collaboration  compounds  known  as  NGM707,  NGM120,  NGM438  and  NGM831,  their  related  compounds  and  all  other
preclinical  and  research  assets  that  we  researched  or  developed  under  our  original  collaboration  agreement  with  Merck  but  that  were  not
included  within  the  R&D  scope  of  the  Amended  Collaboration  Agreement,  which  are  referred  to  as  the  released  NGM  compounds.  Merck
retained the right to receive royalties at low single-digit rates on the sales of any released NGM compounds that receive regulatory approval
and,  if  we  decide  during  a  certain  time  period  to  engage  in  a  formal  partnering  process  for  a  released  NGM  compound  or  negotiations
regarding a license or asset sale of a released NGM compound, we are obligated to notify Merck, provide Merck with certain information and
engage in good faith, non-exclusive negotiations with respect to such released NGM compound with Merck at Merck’s request.

After the research program term, Merck may terminate the overall Amended Collaboration Agreement for convenience upon written
notice. Subject to certain limitations, Merck may partially terminate the Amended Collaboration Agreement for convenience as it relates to
any Licensed Program or any of its rights to research and develop small molecule compounds.

Either  we  or  Merck  may  terminate  the  Amended  Collaboration  Agreement  with  respect  to  a  specific  Licensed  Program  or  any
particular licensed small molecule compound if the other party is in material breach of its obligations regarding that specific program and fails
to cure the breach within the specified cure period. If Merck terminates a Licensed Program as a result of our uncured material breach, then
we would lose our option to participate in a global cost and profit share if not yet exercised as of the time of termination and lose our co-
detailing option (whether or not exercised as of that time) for candidates arising from the relevant Licensed Program. If Merck terminates a
licensed small molecule compound program for our uncured material breach, we would continue to receive the full amount of milestones and
royalties we were otherwise eligible for with respect to the relevant small molecule compounds.

For  additional  information  about  our  collaboration  with  Merck,  see  Note  5,  “Research  Collaboration  and  License  Agreements—

Merck,” in our notes to the consolidated financial statements included in Part II, Item 8 of this Annual Report.

Lonza License

In October 2014, we entered into a Multi-Product License Agreement, or the Lonza License, with Lonza under which we obtained a
worldwide, non-exclusive license to use Lonza’s glutamine synthetase gene expression system, known as GS Xceed , to manufacture and
commercialize our proprietary products.

®

Pursuant to the Lonza License, we paid Lonza an upfront fee of £250,000. Upon the initiation of the first Phase 2 clinical trial, the first
Phase 3 clinical trial and the first commercial sale of any product manufactured using GS Xceed , we are required to pay Lonza one-time
milestone payments of £100,000, £100,000 and £150,000,

®

19

Table of Contents

respectively. We paid a one-time milestone payment to Lonza of £100,000 for each of the Phase 2 trial initiations for NGM313, NGM621 and

NGM120. We are also required to pay low single-digit royalties to Lonza based on net sales of any product manufactured using GS Xceed .
Our royalty obligation to Lonza continues on a product-by-product basis until the later of the expiration of the last-to-expire licensed patent or
ten years after the first commercial sale of the product. We are also required to pay an annual license fee to Lonza of up to £300,000 per
product if a party other than Lonza, we, our affiliates or our strategic partners (including Merck or any potential future partners) manufactures
certain product candidates for commercial activities. We are currently required to pay this fee for NGM313 and NGM120. In accordance with
the Lonza License, for certain additional product candidates, we are instead required to pay an annual license fee to Lonza of £25,000 per
product  candidate  prior  to  the  initiation  of  clinical  development,  and  following  the  initiation  of  clinical  development,  £100,000,  £150,000  or
£300,000 annually per product candidate, respectively, if such product candidate is in a Phase 1, Phase 2 and Phase 3 clinical trial.

The Lonza License continues until the expiration of the royalty term. We have the right to terminate the Lonza License upon written
notice to Lonza. Each party may terminate the Lonza License for the other party’s uncured material breach or bankruptcy. In addition, Lonza
may  terminate  the  Lonza  License  if  we  participate  in  the  opposition  or  challenge  of  any  Lonza  patent  or  patent  application  licensed  to  us
under the Lonza License.

Product Approval in the United States

Government Regulation

The FDA and other regulatory health authorities at federal, state and local levels, as well as in foreign countries, extensively regulate,
among  other  things,  the  research,  development,  testing,  manufacture,  quality  control,  import,  export,  safety,  effectiveness,  labeling,
packaging,  storage,  distribution,  record  keeping,  approval,  advertising,  promotion,  marketing,  post-approval  monitoring  and  post-approval
reporting  of  biologics,  such  as  those  we  are  developing.  We,  along  with  third-party  contractors,  will  be  required  to  navigate  the  various
preclinical,  clinical  and  commercial  approval  requirements  of  the  governing  regulatory  agencies  and  health  authorities  of  the  countries  in
which we wish to conduct studies or seek approval or licensure of our product candidates.

The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, and local statutes and
regulations requires the expenditure of substantial time and financial resources. Failure to comply with the applicable U.S. requirements at
any time during the product development process, approval process or following approval may subject an applicant to administrative actions
or  judicial  sanctions.  These  actions  and  sanctions  could  include,  among  other  actions,  the  FDA’s  refusal  to  approve  pending  applications,
withdrawal  of  an  approval,  license  revocation,  a  clinical  hold,  untitled  or  warning  letters,  voluntary  or  mandatory  product  recalls  or  market
withdrawals,  product  seizures,  total  or  partial  suspension  of  production  or  distribution,  injunctions,  fines,  refusals  of  government  contracts,
restitution,  disgorgement  and  civil  or  criminal  fines  or  penalties.  Any  agency  or  judicial  enforcement  action  could  have  a  material  adverse
effect on our business, the market acceptance of our products and our reputation.

Preclinical and Clinical Development

Prior to beginning the first clinical trial with a product candidate, a sponsor must submit an investigational new drug application, or
IND, to the FDA. An IND is a request for authorization from the FDA to administer an IND product to humans. The central focus of an IND
submission is on the general investigational plan and the protocol(s) for clinical studies. The IND also includes results of animal and in vitro
studies  assessing  the  toxicology,  pharmacology,  pharmacokinetics  and  pharmacodynamic  characteristics  of  the  product;  chemistry,
manufacturing and controls information; and any available human data or literature to support the use of the investigational product. An IND
must become effective before human clinical trials may begin. The IND automatically becomes effective 30 days after receipt by the FDA,
unless the FDA, within the 30-day period, raises concerns or questions regarding safety or conduct of the proposed clinical trial. In such a
case, the IND may be placed on clinical hold and the IND sponsor and the FDA must resolve any outstanding concerns or questions before
the clinical trial can begin. Submission of an IND therefore may or may not result in FDA authorization to begin a clinical trial.

Clinical  trials  involve  the  administration  of  the  investigational  product  to  human  subjects  under  the  supervision  of  qualified
investigators in accordance with current Good Clinical Practices, or cGCPs, which include the requirement that all research subjects provide
their informed consent for their participation in any clinical study. Clinical trials are conducted under protocols detailing, among other things,
the  objectives  of  the  study,  the  parameters  to  be  used  in  monitoring  safety  and  the  effectiveness  criteria  to  be  evaluated.  A  separate
submission  to  the  existing  IND  must  be  made  for  each  successive  clinical  trial  conducted  during  product  development  and  for  any
subsequent protocol amendments. Furthermore, an institutional review board, or IRB, for each site proposing to

20

Table of Contents

conduct the clinical trial must review and approve the plan for any clinical trial and its informed consent form before the clinical trial begins at
that site and must monitor the study until completed.

The FDA, an IRB or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the subjects are
being exposed to an unacceptable health risk or that the trial is unlikely to meet its stated objectives. Some trials also include oversight by an
independent group of qualified experts organized by the clinical study sponsor, known as a data safety monitoring board or committee, which
provides authorization for whether a trial may move forward at designated checkpoints based on access to certain data from the trial and
may halt the clinical trial if it determines that there is an unacceptable safety risk for subjects or other grounds, such as no demonstration of
efficacy. There are also requirements governing the reporting of ongoing clinical studies and clinical study results to public registries.

For  purposes  of  a  biologics  license  application,  or  BLA,  approval,  human  clinical  trials  are  typically  conducted  in  three  sequential

phases that may overlap.

•

•

•

Phase  1—The  investigational  product  is  initially  introduced  into  healthy  human  subjects  or  patients  with  the  target  disease  or
condition.  These  studies  are  designed  to  test  the  safety,  dosage  tolerance,  absorption,  metabolism  and  distribution  of  the
investigational  product  in  humans,  the  side  effects  associated  with  increasing  doses  and,  if  possible,  to  gain  early  evidence  on
effectiveness.

Phase 2—The investigational product is administered to a limited patient population with a specified disease or condition to evaluate
the preliminary efficacy, optimal dosages and dosing schedule and to identify possible adverse side effects and safety risks. Multiple
Phase 2 clinical trials may be conducted to obtain information prior to beginning larger and more expensive Phase 3 clinical trials.

Phase  3—The  investigational  product  is  administered  to  an  expanded  patient  population  to  further  evaluate  dosage,  to  provide
statistically significant evidence of clinical efficacy and to further test for safety, generally at multiple geographically dispersed clinical
trial sites. These clinical trials are intended to establish the overall risk/benefit ratio of the investigational product and to provide an
adequate basis for product approval.

In some cases, the FDA may require, or companies may voluntarily pursue, additional clinical trials after a product is approved to
gain more information about the product. These are called Phase 4 studies and may be made a condition to approval of the BLA. Concurrent
with clinical trials, companies may complete additional animal studies and develop additional information about the biological characteristics
of the product candidate and must finalize a process for manufacturing the product in commercial quantities in accordance with current Good
Manufacturing Practices, or cGMP, requirements. The manufacturing process must be capable of consistently producing quality batches of
the  product  candidate  and,  among  other  things,  for  biologics,  must  develop  methods  for  testing  the  identity,  strength,  quality,  purity  and
potency  of  the  product.  Additionally,  appropriate  packaging  must  be  selected  and  tested  and  stability  studies  must  be  conducted  to
demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life.

BLA Submission and Review

Assuming  successful  completion  of  all  required  testing  in  accordance  with  all  applicable  regulatory  requirements,  the  results  of
product  development,  nonclinical  studies  and  clinical  trials  are  submitted  to  the  FDA  as  part  of  a  BLA  requesting  approval  to  market  the
product for one or more indications. The submission of a BLA requires payment of a substantial application user fee to FDA, unless a waiver
or exemption applies.

Once a BLA has been submitted, the FDA generally decides on the acceptance of the application for filing within 60 days of receipt.
The FDA’s goal is to review standard applications within ten months after it accepts the application for filing, or, if the application qualifies for
priority review, six months after the FDA accepts the application for filing. In both standard and priority reviews, the review process is often
significantly extended by FDA requests for additional information or clarification. The FDA reviews a BLA to determine, among other things,
whether a product is safe, pure and potent and the facility in which it is manufactured, processed, packed or held meets standards designed
to  assure  the  product’s  continued  safety,  purity  and  potency.  The  FDA  may  convene  an  advisory  committee  to  provide  clinical  insight  on
application  review  questions.  Before  approving  a  BLA,  the  FDA  will  typically  inspect  the  facility  or  facilities  where  the  product  is
manufactured.  The  FDA  will  not  approve  an  application  unless  it  determines  that  the  manufacturing  processes  and  facilities  comply  with
cGMP  requirements  and  adequate  to  assure  consistent  production  of  the  product  within  required  specifications.  Additionally,  before
approving a BLA, the FDA will typically inspect one or more clinical sites to assure compliance with cGCPs. If the FDA determines that the
application, manufacturing process or manufacturing facilities are not acceptable, it will outline the deficiencies in the submission and often
will request additional testing or information.

21

Table of Contents

The  FDA  may  issue  an  approval  letter  or  a  Complete  Response  letter.  An  approval  letter  authorizes  commercial  marketing  of  the
product with specific prescribing information for specific indications. A Complete Response letter will describe all deficiencies that the FDA
has identified in the BLA. In issuing the Complete Response letter, the FDA may recommend actions that the applicant might take to place
the  BLA  in  condition  for  approval,  including  requests  for  additional  information  or  clarification,  completion  of  other  significant  and  time-
consuming requirements related to clinical trials, and/or conduct of additional preclinical studies or manufacturing activities. Even if such data
and information are submitted, the FDA may determine that the BLA does not satisfy the criteria for approval. FDA approval of a BLA must
be  obtained  before  a  biologic  may  be  marketed  in  the  United  States.  The  FDA  may  delay  or  refuse  approval  of  a  BLA,  require  additional
testing or information and/or require post-marketing testing and surveillance to monitor safety or efficacy of a product.

If regulatory approval of a product is granted, such approval will be granted for specific indications and may entail limitations on the
indicated uses for which such product may be marketed. For example, the FDA may approve the BLA with a Risk Evaluation and Mitigation
Strategy, or REMS, to ensure the benefits of the product outweigh its risks. A REMS is a safety strategy to manage a known or potential
serious risk associated with a product and to enable patients to have continued access to such medicines by managing their safe use, and
could  include  medication  guides,  physician  communication  plans  or  elements  to  assure  safe  use,  such  as  restricted  distribution  methods,
patient  registries  and  other  risk  minimization  tools.  The  FDA  also  may  condition  approval  on,  among  other  things,  changes  to  proposed
labeling  or  the  development  of  adequate  controls  and  specifications.  Once  approved,  the  FDA  may  withdraw  the  product  approval  if
compliance with pre- and post-marketing requirements is not maintained or if problems occur after the product reaches the marketplace. The
FDA  may  require  one  or  more  Phase  4  post-marketing  studies  and  surveillance  to  further  assess  and  monitor  the  product’s  safety  and
effectiveness after commercialization and may limit further marketing of the product based on the results of these post-marketing studies.

Expedited Programs

A  sponsor  may  seek  to  develop  and  obtain  approval  of  its  product  candidates  under  programs  designed  to  accelerate  the  FDA
review and approval of marketing applications for new drugs and biologics that meet certain criteria, such as the Fast Track program, priority
review, accelerated approval, Breakthrough Therapy designation and Real-Time Oncology Review, or RTOR, Program.

Fast Track Designation

The FDA Fast Track program is intended to facilitate development and expedite review of new drugs and biologics that are intended
to treat a serious or life-threatening disease or condition and that demonstrate potential to address an unmet medical need. For a Fast Track-
designated product, there may be more frequent meetings and communication with the FDA, and early and frequent communication between
the FDA and sponsor is encouraged throughout the entire development and review process. The FDA may consider sections of a BLA for
review on a rolling basis if certain conditions are satisfied, including an agreement with the FDA on the proposed schedule for submission of
portions of the application and the payment of applicable user fees before the FDA may initiate a review. The product may also be eligible for
priority review and accelerated approval. The sponsor can request the FDA to designate the product for Fast Track status any time before
receiving BLA approval, but ideally no later than the pre-BLA meeting.

Priority Review

Generally,  the  FDA  follows  a  two-tiered  system  of  review  times,  standard  review  and  priority  review.  For  a  product  that  receives
priority review designation, the FDA has the goal of acting on the marketing application within six months of the 60-day filing date, compared
to ten months under standard review. However, the FDA does not always meet its PDUFA goal dates for standard and priority BLAs, and the
review  process  is  often  extended  by  FDA  requests  for  additional  information  or  clarification.  A  priority  review  designation  is  applicable  for
products  that,  if  approved,  would  be  significant  improvements  in  the  safety  or  effectiveness  of  the  treatment,  diagnosis,  or  prevention  of
serious  conditions  when  compared  to  marketed  products.  The  FDA  decides  on  the  review  designation  for  every  application;  however,  an
applicant may expressly request priority review. The FDA informs the applicant of a priority review designation within 60 days of the receipt of
the original marketing application. If criteria are not met for priority review, the application is subject to the standard FDA review period of ten
months  after  FDA  accepts  the  application  for  filing.  Priority  review  designation  does  not  change  the  scientific  or  medical  standard  for
approval, or the quality of evidence necessary to support approval.

22

Table of Contents

Accelerated Approval

In addition, the FDA may base accelerated approval for drugs and biologics for serious conditions that fill an unmet medical need on
whether  the  drug  or  biologic  has  an  effect  on  a  surrogate  or  an  intermediate  clinical  endpoint.  A  surrogate  endpoint  used  for  accelerated
approval is a marker, such as a laboratory measurement, radiographic image, physical sign or other measure that is thought to predict clinical
benefit but is not itself a measure of clinical benefit. Likewise, an intermediate clinical endpoint is a measure of a therapeutic effect that is
considered reasonably likely to predict the clinical benefit of a product, such as an effect on irreversible morbidity and mortality, or IMM. The
FDA  bases  its  decision  on  whether  to  accept  the  proposed  surrogate  or  intermediate  clinical  endpoint  on  the  scientific  support  for  that
endpoint.  In  this  regard,  we  are  designing  a  potential  registrational  trial  of  aldafermin  in  PSC  and  continuing  discussions  with  the  FDA,
including  on  the  proposed  utilization  of  a  primary  endpoint  composed  of  surrogate  biomarkers  with  the  goal  of  obtaining  accelerated
approval. There is no guarantee that the FDA will accept our proposed primary endpoint, in which case we may abandon the development of
aldafermin in PSC.

As  a  condition  of  accelerated  approval,  the  FDA  will  generally  require  the  sponsor  to  perform  and  provide  regular  updates  to  the
agency on adequate and well-controlled post-marketing clinical studies to verify and describe the anticipated effect on IMM or other clinical
benefit.  Where  confirmatory  trials  verify  clinical  benefit,  the  FDA  will  generally  terminate  the  requirement.  Approval  of  a  product  may  be
withdrawn or the labeled indication of the product changed, if trials fail to verify clinical benefit or do not demonstrate sufficient clinical benefit
to justify the risks associated with the product, for example, if the product shows a significantly smaller magnitude or duration of benefit than
was  anticipated  based  on  the  observed  effect  on  the  surrogate  endpoint.  In  addition,  the  FDA  currently  requires  as  a  condition  for
accelerated  approval  the  preapproval  of  promotional  materials,  which  could  adversely  impact  the  timing  of  the  commercial  launch  of  the
product.

Breakthrough Therapy Designation

Additionally,  a  drug  or  biologic  may  be  eligible  for  designation  as  a  breakthrough  therapy  if  the  product  is  intended,  alone  or  in
combination  with  one  or  more  other  drugs  or  biologics,  to  treat  a  serious  or  life-threatening  condition  and  preliminary  clinical  evidence
indicates that the product may demonstrate substantial improvement over currently approved therapies on one or more clinically significant
endpoints, such as substantial treatment effects observed early in clinical development. If the FDA designates a breakthrough therapy, it may
take actions appropriate to expedite the development and review of the application, which may include holding meetings with the sponsor
and the review team throughout the development of the therapy; providing timely advice to, and interactive communication with, the sponsor
regarding  the  development  of  the  drug  to  ensure  that  the  development  program  to  gather  the  nonclinical  and  clinical  data  necessary  for
approval  is  as  efficient  as  practicable;  involving  senior  managers  and  experienced  review  staff,  as  appropriate,  in  a  collaborative,  cross-
disciplinary  review;  assigning  a  cross-disciplinary  project  lead  for  the  FDA  review  team  to  facilitate  an  efficient  review  of  the  development
program and to serve as a scientific liaison between the review team and the sponsor; and considering alternative clinical trial designs when
scientifically appropriate, which may result in smaller trials or more efficient trials that require less time to complete and may minimize the
number of patients exposed to a potentially less efficacious treatment. Breakthrough Therapy designation comes with all of the benefits of
Fast  Track  designation,  which  means  that  the  sponsor  may  file  sections  of  the  BLA  for  review  on  a  rolling  basis  if  certain  conditions  are
satisfied, including an agreement with the FDA on the proposed schedule for submission of portions of the application and the payment of
applicable user fees before the FDA may initiate a review.

Real-Time Oncology Review (RTOR) Program

The  RTOR  program  is  for  oncology  product  candidates  that  are  likely  to  demonstrate  substantial  improvements  over  available
therapy,  which  may  include  drugs  previously  granted  Breakthrough  Therapy  designation  for  the  same  or  other  indications  and  candidates
meeting other criteria for other expedited programs, such as Fast Track and priority review. Submissions for RTOR consideration should also
have  straightforward  study  designs  and  endpoints  that  can  be  easily  interpreted  (such  as  overall  survival  or  progression  free  survival).
Acceptance into the RTOR program does not guarantee or influence approvability of the application, which is subject to the usual benefit-risk
evaluation by FDA reviewers, but the program allows FDA to review data earlier, before an applicant formally submits a complete application.
The RTOR program does not affect FDA’s PDUFA timelines.

Even  if  a  product  qualifies  for  one  or  more  of  these  programs,  the  FDA  may  later  decide  that  the  product  no  longer  meets  the
conditions for qualification or the time period for FDA review or approval may not be shortened. Furthermore, Fast Track designation, priority
review, accelerated approval, Breakthrough Therapy designation and RTOR program acceptance do not change the standards for product
approval.

23

Orphan Drug Designation

Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biologic intended to treat a rare disease or condition,
which  is  a  disease  or  condition  that  affects  fewer  than  200,000  individuals  in  the  United  States,  or  more  than  200,000  individuals  in  the
United States for which there is no reasonable expectation that the cost of developing and making available in the United States a drug or
biologic  for  this  type  of  disease  or  condition  will  be  recovered  from  sales  in  the  United  States  for  that  drug  or  biologic.  Orphan  drug
designation must be requested before submitting a BLA. After the FDA grants orphan drug designation, the generic identity of the therapeutic
agent and its potential orphan use are disclosed publicly by the FDA. The orphan drug designation does not convey any advantage in, or
shorten the duration of, the regulatory review or approval process.

If  a  product  that  has  orphan  drug  designation  subsequently  receives  the  first  FDA  approval  for  the  disease  for  which  it  has  such
designation, the product is entitled to orphan drug exclusive approval (or exclusivity), which means that the FDA may not approve any other
applications, including a full BLA, to market the same biologic for the same indication for seven years, except in limited circumstances, such
as a showing of clinical superiority to the product with orphan drug exclusivity by means of greater effectiveness, greater safety or providing a
major  contribution  to  patient  care  or  in  instances  of  drug  supply  issues.  Orphan  drug  exclusivity  does  not  prevent  FDA  from  approving  a
different drug or biologic for the same disease or condition, or the same drug or biologic for a different disease or condition. Among the other
benefits of orphan drug designation are tax credits for certain research and a waiver of the BLA application fee.

A designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for
which it received orphan designation. In addition, exclusive marketing rights in the United States may be lost if the FDA later determines that
the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantities of the product to meet the
needs of patients with the rare disease or condition.

Pediatric Information and Pediatric Exclusivity

Under the Pediatric Research Equity Act, or PREA, certain BLAs and certain supplements to a BLA must contain data to assess the
safety and efficacy of the drug for the claimed indications in all relevant pediatric subpopulations and to support dosing and administration for
each pediatric subpopulation for which the product is safe and effective. The FDA may grant deferrals for submission of pediatric data or full
or  partial  waivers.  A  sponsor  who  is  planning  to  submit  a  marketing  application  for  a  drug  that  includes  a  new  active  ingredient,  new
indication,  new  dosage  form,  new  dosing  regimen  or  new  route  of  administration  must  submit  an  initial  Pediatric  Study  Plan,  or  PSP.  The
initial PSP must include an outline of the pediatric study or studies that the sponsor plans to conduct, including study objectives and design,
age groups, relevant endpoints and statistical approach, or a justification for not including such detailed information, and any request for a
deferral of pediatric assessments or a full or partial waiver of the requirement to provide data from pediatric studies along with supporting
information. The FDA and the sponsor must reach an agreement on the PSP. A sponsor can submit amendments to an agreed-upon initial
PSP at any time if changes to the pediatric plan need to be considered based on data collected from preclinical studies, early phase clinical
trials and/or other clinical development programs.

A drug or biologic product can also obtain pediatric market exclusivity in the United States. Pediatric exclusivity, if granted, adds six
months to existing exclusivity periods and patent terms. This six-month exclusivity, which runs from the end of other exclusivity protection or
patent term, may be granted based on the voluntary completion of a pediatric study in accordance with an FDA-issued “Written Request” for
such a study.

Market Exclusivity under The Biologics Price Competition and Innovation Act of 2009, or BPCIA

Under the BPCIA, sponsors of new, licensed biological products approved through a BLA receive 12 years of “Reference Product
Exclusivity.”  FDA  cannot  license  any  351(k)  application  for  a  biosimilar  or  interchangeable  product  that  relies  on  the  previously  approved
product as a reference for biosimilarity during this 12-year period. This Reference Product Exclusivity does not attach to molecules that are
the “same” as a molecule previously approved for the same sponsor.

Post-Approval Requirements

Any products manufactured or distributed pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA,
including,  among  other  things,  requirements  relating  to  record-keeping,  reporting  of  adverse  experiences,  periodic  reporting,  product
sampling  and  distribution  and  advertising  and  promotion  of  the  product.  After  approval,  most  changes  to  the  approved  product,  such  as
adding new indications or other labeling

24

Table of Contents

claims, are subject to prior FDA review and approval. There also are continuing user fee requirements, under which FDA assesses an annual
program fee for each product identified in an approved BLA.

FDA regulations require that products be manufactured in specific approved facilities and in accordance with cGMP regulations. We
rely, and expect to continue to rely, on third parties to produce clinical and commercial quantities of our products in accordance with cGMP
regulations. These manufacturers must comply with FDA regulations that require, among other things, quality control and quality assurance,
the maintenance of records and documentation and the obligation to investigate and correct any deviations from cGMP. FDA regulations also
impose  reporting  requirements  upon  sponsors  and  their  third-party  manufacturers.  Manufacturers  and  other  entities  involved  in  the
manufacture and distribution of approved biologics are required to register their establishments with the FDA and certain state agencies and
are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP requirements and other
laws, which impose certain procedural and documentation requirements upon sponsors and their third-party manufacturers. The discovery of
violative conditions, including failure to conform to cGMP regulations, could result in enforcement actions, and the discovery of problems with
a product after approval may result in restrictions on a product manufacturer or holder of an approved BLA, and, ultimately in a product recall.
Biologic manufacturers and their subcontractors are required to register their establishments with the FDA and certain state agencies and are
subject  to  periodic  unannounced  inspections  by  the  FDA  and  certain  state  agencies  for  compliance  with  cGMP,  which  impose  certain
procedural and documentation requirements upon sponsors and their third-party manufacturers. Changes to the manufacturing process are
strictly  regulated,  and,  depending  on  the  significance  of  the  change,  may  require  prior  FDA  approval  before  being  implemented.  FDA
regulations  also  require  investigation  and  correction  of  any  deviations  from  cGMP  and  impose  reporting  requirements  upon  sponsors  and
their third-party manufacturers.

The FDA may also place other conditions on approvals including the requirement for a REMS, to assure the safe use of the product.
If the FDA concludes a REMS is needed, the sponsor of the BLA must submit a proposed REMS. The FDA will not approve the BLA without
an approved REMS, if required. A REMS could include medication guides, physician communication plans or elements to assure safe use,
such as restricted distribution methods, patient registries and other risk minimization tools. Any of these limitations on approval or marketing
could  restrict  the  commercial  promotion,  distribution,  prescription  or  dispensing  of  products.  Product  approvals  may  be  withdrawn  for
noncompliance with regulatory standards or if problems occur following initial marketing. The FDA may withdraw approval if compliance with
regulatory  requirements  and  standards  is  not  maintained  or  if  problems  occur  after  the  product  reaches  the  market.  Later  discovery  of
previously  unknown  problems  with  a  product,  including  adverse  events  of  unanticipated  severity  or  frequency,  or  with  manufacturing
processes, or failure to comply with regulatory requirements, may result in: revisions to the approved labeling to add new safety information,
imposition  of  post-market  studies  or  clinical  studies  to  assess  new  safety  risks,  or  imposition  of  distribution  or  other  restrictions  under  a
REMS program. Other potential consequences include, among other things:

•

•

•

•

•

restrictions on the marketing or manufacturing of a product, complete withdrawal of the product from the market or product recalls;

fines, warning letters or holds on post-approval clinical studies;

refusal of the FDA to approve pending applications or supplements to approved applications, or suspension or revocation of existing
product approvals;

product seizure or detention, or refusal of the FDA to permit the import or export of products; or

injunctions or the imposition of civil or criminal penalties.

The FDA closely regulates the marketing, labeling, advertising and promotion of biologics. A company can make only those claims
relating to safety and efficacy, purity and potency that are approved by the FDA and in accordance with the provisions of the approved label.
The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses and misbranding. Failure to
comply with these requirements can result in, among other things, adverse publicity, warning letters, corrective actions, including corrective
advertising, and potential civil and criminal penalties, including monetary penalties. Physicians may prescribe legally available products for
uses  that  are  not  described  in  the  product’s  labeling  and  that  differ  from  those  tested  and  approved  by  the  FDA.  Such  off-label  uses  are
common  across  medical  specialties.  Physicians  may  believe  that  such  off-label  uses  are  the  best  treatment  for  many  patients  in  varied
circumstances.  The  FDA  does  not  regulate  the  behavior  of  physicians  in  their  choice  of  treatments.  The  FDA  does,  however,  restrict
manufacturer’s communications on the subject of off-label use of their products, and a company that is found to have improperly promoted
off-label  uses  may  be  subject  to  significant  liability,  including  investigation  by  federal  and  state  authorities.  Prescription  drug  promotional
materials  must  be  submitted  to  the  FDA  in  conjunction  with  their  first  use  or  first  publication  (or  thirty  days  in  advance  of  their  first  use  if
approved  via  the  accelerated  approval  pathway).  Further,  if  there  are  any  modifications  to  the  drug  or  biologic,  including  changes  in
indications, labeling or manufacturing

25

Table of Contents

processes  or  facilities,  the  applicant  may  be  required  to  submit  and  obtain  FDA  approval  of  a  new  BLA  or  BLA  supplement,  which  may
require the development of additional data or preclinical studies and clinical trials.

Other U.S. Healthcare Laws and Compliance Requirements

In the United States, our current and future operations are subject to regulation by various federal, state and local authorities. For
example, our clinical research, sales, marketing and scientific/educational grant programs may have to comply with the anti-fraud and abuse
provisions  of  the  Social  Security  Act,  the  federal  Anti-Kickback  Statute,  the  false  claims  laws,  the  privacy  and  security  provisions  of  the
Health Insurance Portability and Accountability Act, or HIPAA, and similar state laws, each as amended, as applicable.

The federal Anti-Kickback Statute prohibits, among other things, any person or entity, from knowingly and willfully offering, paying,
soliciting  or  receiving  any  remuneration,  directly  or  indirectly,  overtly  or  covertly,  in  cash  or  in  kind,  to  induce  or  in  return  for  purchasing,
leasing,  ordering  or  arranging  for  the  purchase,  lease  or  order  of  any  item  or  service  reimbursable,  in  whole  or  in  part,  under  Medicare,
Medicaid or other federal healthcare programs. The term remuneration has been interpreted broadly to include anything of value. There are a
number of statutory exceptions and regulatory safe harbors protecting some common activities from prosecution. The exceptions and safe
harbors are drawn narrowly and practices that involve remuneration that may be alleged to be intended to induce prescribing, purchasing or
recommending may be subject to scrutiny if they do not qualify for an exception or safe harbor. Failure to meet all of the requirements of a
particular applicable statutory exception or regulatory safe harbor does not make the conduct per se illegal under the Anti-Kickback Statute.
Instead,  the  legality  of  the  arrangement  will  be  evaluated  on  a  case-by-case  basis  based  on  a  cumulative  review  of  all  of  its  facts  and
circumstances. Our practices may not in all cases meet all the criteria for protection under a statutory exception or regulatory safe harbor.

Additionally, the intent standard under the Anti-Kickback Statute was amended by the Patient Protection and Affordable Care Act, as
amended by the Health Care and Education Reconciliation Act, collectively referred to as the ACA, to impose a stricter standard such that a
person or entity no longer needs to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation.
In addition, the ACA codified case law that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute
constitutes a false or fraudulent claim for purposes of the federal False Claims Act, or FCA.

The federal false claims and civil monetary penalty laws, including the FCA, which imposes significant penalties and can be enforced
by private citizens through civil qui tam actions, prohibit any person or entity from, among other things, knowingly presenting, or causing to be
presented, a false or fraudulent claim for payment to, or approval by, the federal government, including federal healthcare programs, such as
Medicare and Medicaid, knowingly making, using or causing to be made or used a false record or statement material to a false or fraudulent
claim to the federal government, or knowingly making a false statement to improperly avoid, decrease or conceal an obligation to pay money
to the federal government. A claim includes “any request or demand” for money or property presented to the U.S. government.

HIPAA created additional federal criminal statutes that prohibit, among other things, knowingly and willfully executing, or attempting
to execute, a scheme to defraud or to obtain, by means of false or fraudulent pretenses, representations or promises, any money or property
owned  by,  or  under  the  control  or  custody  of,  any  healthcare  benefit  program,  including  private  third-party  payors,  willfully  obstructing  a
criminal investigation of a healthcare offense and knowingly and willfully falsifying, concealing or covering up by trick, scheme or device, a
material  fact  or  making  any  materially  false,  fictitious  or  fraudulent  statement  in  connection  with  the  delivery  of  or  payment  for  healthcare
benefits, items or services. Like the Anti-Kickback Statute, the ACA amended the intent standard for certain healthcare fraud statutes under
HIPAA such that a person or entity no longer needs to have actual knowledge of the statute or specific intent to violate it in order to have
committed a violation.

Also,  many  states  have  similar,  and  typically  more  prohibitive,  fraud  and  abuse  statutes  or  regulations  that  apply  to  items  and

services reimbursed under Medicaid and other state programs, or, in several states, apply regardless of the payor.

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, and its implementing
regulations, imposes requirements on covered entities (including certain health care providers, health plans and health care clearinghouses,
business  associates  and  their  covered  subcontractors)  relating  to  the  privacy,  security  and  transmission  of  individually  identifiable  health
information. HIPAA may be enforced by several federal agencies as well as state attorneys general. In addition, many state laws govern the
privacy and security of health information in specified circumstances, many of which differ from each other in significant ways, are often not
preempted by HIPAA and may have a more prohibitive effect than HIPAA, thus complicating compliance efforts.

Our  physician-administered  products,  if  approved,  may  be  eligible  for  coverage  under  Medicare  through  Medicare  Part  B.  As  a
condition of receiving Medicare Part B reimbursement for a manufacturer’s eligible drugs, the manufacturer is required to participate in other
government healthcare programs, including the Medicaid Drug Rebate Program and the 340B Drug Pricing Program, and would be subject to
those requirements as well.

In addition, many pharmaceutical manufacturers must calculate and report certain price reporting metrics to the government, such as
average sales price and best price. Penalties may apply in some cases when such metrics are not submitted accurately and timely. Further,
these prices for drugs may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors
and by any future relaxation of laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the
United States.

Additionally,  the  federal  Physician  Payments  Sunshine  Act,  or  the  Sunshine  Act,  as  amended,  and  its  implementing  regulations,
require  that  certain  manufacturers  of  drugs,  devices,  biological  and  medical  supplies  for  which  payment  is  available  under  Medicare,
Medicaid  or  the  Children’s  Health  Insurance  Program  (with  certain  exceptions)  report  annually  to  CMS  information  related  to  certain
payments  or  other  transfers  of  value  made  or  distributed  to  physicians  (defined  to  include  doctors,  dentists,  optometrists,  podiatrists  and
chiropractors),  other  health  care  professionals  (such  as  physician  assistants  and  nurse  practitioners)  and  teaching  hospitals,  as  well  as
information regarding ownership and investment interests held by physicians and their immediate family members.

In addition, many states also govern the reporting of such payments or other transfers of value, many of which differ from each other
in  significant  ways,  are  often  not  preempted  and  may  have  a  more  prohibitive  effect  than  the  Sunshine  Act,  thus  further  complicating
compliance efforts.

In  order  to  distribute  products  commercially,  we  must  comply  with  state  laws  that  require  the  registration  of  manufacturers  and
wholesale distributors of drug and biological products in a state, including, in certain states, manufacturers and distributors who ship products
into the state even if such manufacturers or distributors have no place of business within the state. Some states also impose requirements on
manufacturers  and  distributors  to  establish  the  pedigree  of  product  in  the  chain  of  distribution,  including  some  states  that  require
manufacturers and others to adopt new technology capable of tracking and tracing product as it moves through the distribution chain. Several
states  have  enacted  legislation  requiring  pharmaceutical  and  biotechnology  companies  to  establish  marketing  compliance  programs,  file
periodic reports with the state, make periodic public disclosures on sales, marketing, pricing, clinical trials and other activities and/or register
their sales representatives, as well as to prohibit pharmacies and other healthcare entities from providing certain physician prescribing data
to pharmaceutical and biotechnology companies for use in sales and marketing, and to prohibit certain other sales and marketing practices.
Our activities are potentially subject to federal and state consumer protection and unfair competition laws.

The scope and enforcement of each of these laws is uncertain and subject to rapid change in the current environment of healthcare
reform, especially in light of the lack of applicable precedent and regulations. Ensuring business arrangements with third parties comply with
applicable healthcare laws and regulations is a costly endeavor. If our operations are found to be in violation of any of the federal and state
healthcare laws described above or any other current or future governmental regulations that apply to us, we may be subject to penalties,
including without limitation, civil, criminal and/or administrative penalties, damages, fines, disgorgement, individual imprisonment, exclusion
from  participation  in  government  programs,  such  as  Medicare  and  Medicaid,  injunctions,  private  qui  tam  actions  brought  by  individual
whistleblowers  in  the  name  of  the  government,  refusal  to  allow  us  to  enter  into  government  contracts,  contractual  damages,  reputational
harm, administrative burdens, diminished profits and future earnings, additional reporting obligations and oversight if we become subject to a
corporate  integrity  agreement  or  other  agreement  to  resolve  allegations  of  noncompliance  with  these  laws,  and  the  curtailment  or
restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations.

The Foreign Corrupt Practices Act

The Foreign Corrupt Practices Act, or FCPA, prohibits any U.S. individual or business from paying, offering or authorizing payment or
offering of anything of value, directly or indirectly, to any foreign official, political party or candidate for the purpose of influencing any act or
decision  of  the  foreign  entity  in  order  to  assist  the  individual  or  business  in  obtaining  or  retaining  business.  The  FCPA  also  obligates
companies whose securities are listed in the United States to comply with accounting provisions requiring us to maintain books and records
that  accurately  and  fairly  reflect  all  transactions  of  the  corporation,  including  international  subsidiaries,  and  to  devise  and  maintain  an
adequate system of internal accounting controls for international operations.

Environmental, Health and Safety Regulation

In  addition  to  the  foregoing,  state  and  federal  laws  regarding  safe  working  conditions,  environmental  protection  and  hazardous
substances,  including  the  Occupational  Safety  and  Health  Act,  the  Resource  Conservancy  and  Recovery  Act  and  the  Toxic  Substances
Control Act, affect our business. These and other laws govern our use, handling and disposal of various biological, chemical and radioactive
substances used in, and wastes generated by, our operations. We may incur significant costs to comply with such laws and regulations now
or  in  the  future.  If  our  operations  result  in  contamination  of  the  environment  or  expose  individuals  to  hazardous  substances,  we  could  be
liable  for  damages  and  governmental  fines.  We  believe  that  we  are  in  material  compliance  with  applicable  environmental  laws  and
regulations and that continued compliance therewith will not have a material adverse effect on our business. We cannot predict, however,
how changes in these laws and regulations may affect our future operations.

European Union Development of Medicinal Products

In  the  European  Economic  Area,  or  EEA,  which  consists  of  the  27  Member  States  of  the  European  Union,  or  the  EU  and  the  EU
Member  States,  as  well  as  Norway,  Iceland  and  Liechtenstein,  medicinal  products  can  only  be  commercialized  after  a  marketing
authorization, or MA, has been granted by a competent regulatory authority. This is similar to the approach in the United States. Clinical trials
in the EEA are currently regulated by Clinical Trials Regulation (EU) No 536/2014, or CTR, which entered into application on January 31,
2022. The regulation, which is directly applicable in all EEA countries, overhauls the previous system of approvals for clinical trials in the EU
to simplify and streamline the approval of clinical trials in the EU.

European Union Review of Marketing Authorization and Approval

Depending  on  the  type  of  product  and  its  intended  therapeutic  indication,  related  MAs  may  be  granted  either  by  the  European
Commission  at  the  EU  level  or  by  the  competent  authorities  of  EEA  countries.  An  MA  issued  by  the  European  Commission  through  the
Centralized  Procedure,  based  on  the  opinion  of  the  Committee  for  Medicinal  Products  for  Human  Use,  or  CHMP,  of  the  EMA,  is  valid
throughout  the  entire  territory  of  the  EEA.  The  Centralized  Procedure  is  mandatory  for  certain  types  of  products,  such  as  biotechnology
medicinal  products,  orphan  medicinal  products,  advanced-therapy  medicines  such  as  gene-therapy,  somatic  cell-therapy  or  tissue-
engineered  medicines  and  medicinal  products  containing  a  new  active  substance  indicated  for  the  treatment  of  HIV,  AIDS,  cancer,
neurodegenerative  disorders,  diabetes,  autoimmune  and  other  immune  dysfunctions  and  viral  diseases.  The  Centralized  Procedure  is
optional, subject to the approval of the EMA, for products containing a new active substance not yet authorized in the EEA for the treatment
of  diseases  other  than  those  indicated  above,  or  for  products  that  constitute  a  significant  therapeutic,  scientific  or  technical  innovation  or
which are in the interest of public health in the EU.

National  MAs,  which  are  issued  by  the  competent  authorities  of  the  EEA  countries,  and  only  cover  their  respective  territory,  are
available for products not falling within the mandatory scope of the Centralized Procedure. Where a product has already been authorized for
marketing in an EEA country, that National MA can be recognized in another EEA country through the Mutual Recognition Procedure. If the
product has not received a National MA in any EEA country at the time of application for authorization, it can be approved simultaneously in
various  EEA  countries  through  the  Decentralized  Procedure.  Under  the  Decentralized  Procedure,  an  identical  dossier  is  submitted  to  the
competent authorities of each of the EEA countries in which the MA is sought, one of which is selected by the applicant as the Reference
Member  State,  or  RMS.  The  competent  authority  of  the  RMS  prepares  a  draft  assessment  report,  a  draft  Summary  of  Product
Characteristics, or SmPC, the document that provides information to physicians concerning the safe and effective use of the product, and a
draft of the labeling and package leaflet, which are sent to the other EEA countries, referred to as the Concerned Member States, or CMSs,
for their approval. If the CMSs raise no objections to the assessment, SmPC, labeling or packaging proposed by the RMS, the product is
subsequently  granted  a  National  MA  in  the  RMS  and  the  Concerned  Member  States.  The  RMS  or  CMSs  may  only  raise  objections  to
authorization that are based on a potential serious risk to public health.

In the EEA, an MA, whether granted through the Centralized, Decentralized or Mutual Recognition Procedures, may be granted only

to an MA applicant that is established within the EEA.

In principle, an MA has an initial validity of five years. The MA may be renewed after five years based on a re-evaluation of the risk-
benefit  balance  by  the  EMA  or  by  the  competent  authority  of  the  EEA  country  in  which  the  original  MA  was  granted.  The  European
Commission or the competent authorities of the EEA country may decide, on justified grounds relating to pharmacovigilance, to require one
additional  five-year  period  for  the  MA  before  it  is  definitively  renewed.  Once  subsequently  definitively  renewed,  the  MA  is  valid  for  an
unlimited  period.  Any  MA  that  is  not  followed  by  the  actual  placing  of  the  medicinal  product  on  the  EEA  market  (in  case  of  Centralized
Procedure

28

Table of Contents

approvals), or on the market of the authorizing EEA country if applicable, within three years after authorization ceases to be valid (the so-
called sunset clause).

Innovative  products  that  target  an  unmet  medical  need  and  are  expected  to  be  of  major  public  health  interest  may  be  eligible  for
several expedited development and review programs, such as the Priority Medicines, or PRIME, scheme, which provides incentives similar to
the  Breakthrough  Therapy  designation  in  the  United  States.  In  the  EEA,  a  conditional  MA  may  be  granted  by  the  European  Commission
through the Centralized Procedure in cases where all the required safety and efficacy data are not yet available. Eligible products must fulfill
specific  criteria  and  the  conditional  MA  is  subject  to  conditions  to  be  fulfilled  concerning  generation  of  missing  data  or  ensuring  increased
safety  measures.  It  is  valid  for  one  year  and  must  be  renewed  annually  until  all  related  conditions  have  been  fulfilled.  After  this,  the
conditional MA may be converted to a normal MA.

An  MA  may  also  be  granted  “under  exceptional  circumstances”  by  the  European  Commission  through  the  Centralized  Procedure
where the MA applicant can show that it is unable to provide comprehensive data on the efficacy and safety of the medicinal product under
normal  conditions  of  use  even  after  the  product  has  been  authorized  and  subject  to  specific  procedures  after  being  introduced.  These
circumstances may arise in particular when the intended therapeutic indications are very rare and, based on the state of scientific knowledge
at that time, it is not possible to provide comprehensive information, or when generating data may be contrary to generally accepted ethical
principles. An applicant for authorization in exceptional circumstances is not subsequently required to provide the missing data. Although the
MA “under exceptional circumstances” is granted definitively, the risk-benefit balance of the medicinal product is reviewed annually, and the
MA will be withdrawn if the risk-benefit ratio is no longer favorable.

Data and Market Exclusivity

The EU legislation governing the grant of marketing authorizations for medicinal products also provides opportunities for data and
market exclusivity related to MAs in certain circumstances. Upon grant of an MA, innovative medicinal products generally benefit from eight
years  of  data  exclusivity  and  ten  years  of  market  exclusivity.  Data  exclusivity,  if  granted,  prevents  regulatory  authorities  in  the  EEA  from
referencing  the  innovator’s  data  to  assess  a  biosimilar  application  for  eight  years  from  the  date  of  authorization  of  the  innovative  product,
after  which  a  biosimilar  application  for  MA  can  be  submitted,  and  the  innovator’s  data  may  be  referenced.  The  market  exclusivity  period
prevents a successful biosimilar applicant from commercializing its product in the EEA until ten years have elapsed from the initial MA of the
innovator product in the EEA. The overall ten-year period may, occasionally, be extended for a further year to a maximum of eleven years if,
during  the  first  eight  years  of  those  ten  years,  the  MA  holder  obtains  an  authorization  for  one  or  more  new  therapeutic  indications  which,
during the scientific evaluation prior to their authorization, are held to bring a significant clinical benefit in comparison with existing therapies.
There  is,  however,  no  guarantee  that  our  products  will  be  considered  by  EU  regulatory  authorities  to  be  a  new  biological  entity.  In  such
circumstances, our products, even if granted MA, may not qualify for data and market exclusivity.

Pediatric Development

Regulation (EC) No 1901/2006 provides that all applications for an MA for new medicinal products have to include the results of trials
conducted in the pediatric population in compliance with a pediatric investigation plan, or PIP, agreed to with the EMA’s Pediatric Committee,
or PDCO. The PIP sets out the timing and measures proposed to generate data to support a pediatric indication of the medicinal product for
which MA is being sought.

The  PDCO  can  grant  a  deferral  of  the  obligation  to  implement  some  or  all  of  the  measures  provided  in  the  PIP  until  there  are
sufficient  data  to  demonstrate  the  efficacy  and  safety  of  the  product  in  adults.  The  obligation  to  provide  pediatric  clinical  trial  data  can  be
waived  entirely  by  the  PDCO  when  these  data  are  not  needed  or  appropriate  because  the  product  is  likely  to  be  ineffective  or  unsafe  in
children, the disease or condition for which the product is intended occurs only in adult populations, or when the product does not represent a
significant therapeutic benefit over existing treatments for pediatric patients. Once the MA is obtained in all EEA countries and study results
in compliance with the PIP are included in the product information, even when those results are negative, the product may be eligible for a
six-month  extension  to  certain  patent  protections  or,  in  the  case  of  orphan  medicinal  products,  a  two-year  extension  of  orphan  market
exclusivity.

Orphan Designation

In the EU, Regulation (EC) No. 141/2000, as implemented by Regulation (EC) No. 847/2000, provides that a medicinal product can
be designated as an orphan medicinal product by the European Commission if its sponsor can establish that: (i) the product is intended for
the diagnosis, prevention or treatment of life-threatening or chronically debilitating conditions; (ii) either (a) such conditions affect not more
than 5 in 10,000 persons in the EU

29

Table of Contents

when the application is made, or (b) the product, without the benefits derived from orphan status, would not generate sufficient return in the
EU  to  justify  the  necessary  investment  in  developing  the  medicinal  product;  and  (iii)  there  exists  no  satisfactory  authorized  method  of
diagnosis, prevention or treatment of the condition that has been authorized in the EU, or even if such method exists, the product will be of
significant benefit to those affected by that condition.

Regulation (EC) No 847/2000 sets out further provisions for implementation of the criteria for designation of a medicinal product as
an orphan medicinal product. An application for the designation of a medicinal product as an orphan medicinal product must be submitted at
any stage of development of the medicinal product but before filing of an MA application. An MA for an orphan medicinal product may only
include  indications  designated  as  orphan.  For  non-orphan  indications  treated  with  the  same  active  pharmaceutical  ingredient,  a  separate
marketing authorization must be sought.

Orphan medicinal product designation entitles an applicant to incentives such as fee reductions or fee waivers, protocol assistance
and  access  to  the  centralized  marketing  authorization  procedure.  Upon  grant  of  a  marketing  authorization,  orphan  medicinal  products  are
entitled to a ten-year period of market exclusivity for the approved therapeutic indication, which means that the EMA cannot accept another
marketing  authorization  application  or  accept  an  application  to  extend  for  a  similar  product  and  the  European  Commission  cannot  grant  a
marketing authorization for the same indication for a period of ten years. The period of market exclusivity is extended by two years for orphan
medicinal  products  that  have  also  complied  with  an  agreed  upon  PIP.  No  extension  to  any  supplementary  protection  certificate  can  be
granted on the basis of pediatric studies for orphan indications. Orphan medicinal product designation does not convey any advantage in, or
shorten the duration of, the regulatory review and approval process.

The period of market exclusivity may, however, be reduced to six years if, at the end of the fifth year, it is established that the product
no longer meets the criteria on the basis of which it received orphan medicinal product destination, including where it can be demonstrated
on  the  basis  of  available  evidence  that  the  original  orphan  medicinal  product  is  sufficiently  profitable  not  to  justify  maintenance  of  market
exclusivity  or  where  the  prevalence  of  the  condition  has  increased  above  the  threshold.  Additionally,  an  MA  may  be  granted  to  a  similar
medicinal  product  with  the  same  orphan  indication  during  the  ten-year  period  if:  (i)  if  the  applicant  consents  to  a  second  original  orphan
medicinal product application, (ii) if the manufacturer of the original orphan medicinal product is unable to supply sufficient quantities; or (iii) if
the  second  applicant  can  establish  that  its  product,  although  similar,  is  safer,  more  effective  or  otherwise  clinically  superior  to  the  original
orphan medicinal product. A company may voluntarily remove a product from the register of orphan products.

Post-Approval Requirements

Both  MA  holders  and  manufacturers  of  medicinal  products  are  subject  to  comprehensive  regulatory  oversight  by  the  EMA,  the
European  Commission  and/or  the  competent  regulatory  authorities  of  the  individual  EEA  countries  and  regional  authorities  within  those
countries. Legislation adopted at the EU level, such as Directives, may be implemented differently by individual EEA countries. Examples of
post-approval requirements include the obligation on the holder of an MA to comply with a range of regulatory requirements applicable to the
manufacturing,  marketing,  promotion  and  sale  of  medicinal  products,  establish  and  maintain  a  pharmacovigilance  system  and  appoint  an
individual qualified person for pharmacovigilance who is responsible for oversight of that system. Key obligations include expedited reporting
of suspected serious adverse reactions and submission of periodic safety update reports, or PSURs. All new applicants for MA must include
a risk management plan, or RMP, describing the risk management system that the company will put in place and documenting measures to
prevent or minimize the risks associated with the product. The regulatory authorities may also impose risk-minimization measures or post-
authorization obligations as a condition of the MA, which may include additional safety monitoring, more frequent submission of PSURs or
the conduct of additional clinical trials or post-authorization safety studies.

Marketing of Medicinal Products in the EEA

In the EEA, the advertising and promotion of medicinal products are subject to both EU law and the national law of individual EEA
countries  governing  promotion  of  medicinal  products,  interactions  with  physicians  and  other  healthcare  professionals,  misleading  and
comparative advertising and unfair commercial practices. Although general requirements for advertising and promotion of medicinal products
are established at the EU level, the details are governed by rules developed in individual EEA countries and can differ from one country to
another.  Examples  of  regulatory  obligations  include  the  requirement  that  promotional  materials  and  advertising  in  relation  to  medicinal
products  comply  with  the  product’s  SmPC  as  approved  by  the  competent  authorities  in  connection  with  an  MA.  Promotion  materials  and
advertising may also require approval by competent authorities in certain EEA

30

Table of Contents

countries. Promotional activity that does not comply with the SmPC is considered off-label and is prohibited in the EU. Direct-to-consumer
advertising of prescription medicinal products is also prohibited in the EU.

Marketed  products  in  the  EEA  are  subject  to  substantial  continuing  regulation.  This  includes,  among  other  things,  requirements
relating  to  record-keeping,  reporting  of  adverse  experiences,  periodic  reporting,  product  sampling  and  distribution  and  advertising  and
promotion  of  the  product.  For  example,  the  provision  of  benefits  or  advantages  to  physicians  to  induce  or  encourage  the  prescription,
recommendation, endorsement, purchase, supply, order or use of medicinal products is prohibited in the EEA. The provision of benefits or
advantages to physicians is governed by national laws, including national anti-bribery laws, national sunshine rules, regulations, industry self-
regulation  codes  or  professional  codes  of  conduct  and  related  national  implementing  laws.  Payments  made  to  physicians  in  certain  EEA
countries  must  also  be  publicly  disclosed,  and  agreements  with  physicians  may  be  subject  to  prior  notification  and  approval  by  the
physician’s employer, his or her competent professional organization and/or the regulatory authorities of the individual EEA countries. Failure
to comply with these requirements could result in reputational risk, public reprimands, administrative penalties, fines or imprisonment.

Regulation in the United Kingdom Following Brexit

The  United  Kingdom’s,  or  UK's,  withdrawal  from  the  EU  on  January  31,  2020,  commonly  referred  to  as  Brexit,  has  changed  the
regulatory relationship between the UK and the EU. The Medicines and Healthcare products Regulatory Agency, or MHRA, is now the UK’s
standalone regulator for medicinal products and medical devices. Great Britain (England, Scotland and Wales) is now a third country to the
EU. Northern Ireland will, with regard to EU regulations, continue to follow the EU regulatory rules for now.

The UK regulatory framework in relation to clinical trials is governed by the Medicines for Human Use (Clinical Trials) Regulations
2004, as amended, which is derived from the Clinical Trials Directive, as implemented into UK national law through secondary legislation. On
January  17,  2022,  the  MHRA  launched  an  eight-week  consultation  on  reframing  the  UK  legislation  for  clinical  trials,  and  which  aimed  to
streamline  clinical  trials  approvals,  enable  innovation,  enhance  clinical  trials  transparency,  enable  greater  risk  proportionality,  and  promote
patient and public involvement in clinical trials. The UK Government published its response to the consultation on March 21, 2023, confirming
that it would bring forward changes to the legislation. These resulting legislative amendments will determine how closely the UK regulations
will  align  with  the  CTR.  In  October  2023,  the  MHRA  announced  a  new  Notification  Scheme  for  clinical  trials  which  enables  a  more
streamlined and risk-proportionate approach to initial clinical trial applications for Phase 4 and low-risk Phase 3 clinical trial applications.

Marketing authorizations in the UK are governed by the Human Medicines Regulations (SI 2012/1916), as amended. Since January
1, 2021, an applicant for the EU centralized procedure marketing authorization can no longer be established in the UK. As a result, since this
date, companies established in the UK cannot use the EU centralized procedure and instead must follow one of the UK national authorization
procedures or one of the remaining post-Brexit international cooperation procedures to obtain a marketing authorization to market products in
the  UK.  All  existing  EU  marketing  authorizations  for  centrally  authorized  products  were  automatically  converted  or  grandfathered  into  UK
marketing authorization, effective in Great Britain only, free of charge on January 1, 2021, unless the marketing authorization holder opted-
out of this possibility. Northern Ireland currently remains within the scope of EU authorizations in relation to centrally authorized medicinal
products. Accordingly, until the Windsor Framework is implemented in Northern Ireland on January 1, 2025, products falling within the scope
of the EU centralized procedure can only be authorized through UK national authorization procedures in Great Britain.

The MHRA has also introduced changes to national marketing authorization procedures. This includes introduction of procedures to
prioritize  access  to  new  medicines  that  will  benefit  patients,  including  a  150-day  assessment  route,  a  rolling  review  procedure  and  the
International Recognition Procedure. Since January 1, 2024, the MHRA may rely on the International Recognition Procedure, or IRP, when
reviewing  certain  types  of  marketing  authorization  applications.  This  procedure  is  available  for  applicants  for  marketing  authorization  who
have  already  received  an  authorization  for  the  same  product  from  a  reference  regulator.  These  include  the  FDA,  the  EMA  and  national
competent authorities of individual EEA countries. A positive opinion from the EMA and CHMP, or a positive end of procedure outcome from
the mutual recognition or decentralized procedures, are considered to be authorizations for the purposes of the IRP.

There  is  no  pre-marketing  authorization  orphan  designation  for  medicinal  products  in  the  UK.  Instead,  the  MHRA  reviews
applications for orphan designation in parallel to the corresponding marketing authorization application. The criteria are essentially the same
as those in the EU but have been tailored for the market. This includes the criterion that prevalence of the condition in Great Britain, rather
than the EU, must not be more than five in 10,000. Upon the grant of a marketing authorization with orphan status, the medicinal product will
benefit

from up to ten years of market exclusivity from similar products in the approved orphan indication. The start of this market exclusivity period
will be set from the date of first approval of the product in Great Britain.

Privacy and Data Security Laws and Compliance Obligations

In  the  ordinary  course  of  our  business,  we  may  process  personal  or  sensitive  data  (including  health-related  data,  such  as  data
related to oncology, retinal disease and liver and metabolic disease, as part of our clinical trial and drug discovery activities). Accordingly, we
are, or may become, subject to numerous obligations, including U.S. federal, state and local, as well as foreign, data privacy and security
laws, regulations, guidance and industry standards, and other legal obligations related to privacy and data security. The regulatory framework
with respect to data privacy and security is stringent and constantly evolving. For example, in addition to laws such as HIPAA that govern the
processing  of  health  information,  we  are  or  may  become  subject  to  numerous  other  data  privacy  and  security  laws  and  legal  obligations,
which may include laws such as the Federal Trade Commission Act, the California Consumer Privacy Act of 2018, or CCPA, the California
Privacy  Rights  Act  of  2020,  or  CPRA,  and  similar  laws  enacted  or  proposed  in  other  states  in  the  United  States,  the  EU’s  General  Data
Protection Regulation 2016/679, or EU GDPR, and the EU GDPR as it forms part of UK law by virtue of section 3 of the European Union
(Withdrawal) Act 2018, or UK GDPR, together referred to as the GDPR. Additionally, we are, or may become, subject to various U.S. federal
and state consumer protection laws which require us to publish statements that accurately and fairly describe how we handle personal data
and choices individuals may have about the way we handle their personal data.

These laws and obligations impose on subject entities extensive, costly and complex compliance obligations, which may conflict or
be inconsistent with one another, and violations may result in significant fines, penalties and other adverse consequences. The CCPA and
GDPR are examples of the increasingly stringent and evolving regulatory frameworks related to personal data processing that may increase
our  compliance  obligations  and  exposure  for  any  noncompliance.  For  example,  the  CCPA  imposes  obligations  on  covered  businesses  to
provide  specific  disclosures  related  to  a  business’s  collecting,  using  and  disclosing  personal  data  and  to  respond  to  certain  requests  from
California residents related to their personal data. Also, the CCPA provides for civil penalties and a private right of action for data breaches
which may include an award of statutory damages. In addition, the CPRA, effective January 1, 2023, expanded the CCPA to, among other
things,  give  California  residents  the  ability  to  limit  use  of  certain  sensitive  personal  data,  establish  restrictions  on  personal  data  retention,
expand the types of data breaches that are subject to the CCPA’s private right of action and establish a new California Privacy Protection
Agency to implement and enforce the new law.

Foreign  data  privacy  and  security  laws  (including  but  not  limited  to  the  GDPR)  impose  significant  and  complex  compliance
obligations on entities that are subject to those laws, including companies established outside the EEA and/or the UK that process personal
data in connection with the offering of goods or services to data subjects in the EEA/UK or the monitoring of the behavior of data subjects in
the  EEA.  These  obligations  include:  limiting  personal  data  processing  to  only  what  is  necessary  for  specified,  explicit  and  legitimate
purposes;  establishing  a  legal  basis  for  personal  data  processing;  appointing  a  data  protection  officer  in  certain  circumstances;  facilitating
data  subject  requests;  conducting  data  protection  impact  assessments  in  certain  circumstances;  limiting  the  collection  and  retention  of
personal  data;  implementing  and  maintaining  appropriate  technical  and  organizational  safeguards  for  personal  data;  notifying  certain
personal data breaches to the relevant supervisory authorities and affected individuals; and appointing a representative in the EU and/or the
UK.

See “Risk Factors—Risks Related to Our Business and Industry” for additional information about the privacy and data security risks

we may face, including in relation to the laws and regulations to which we are or may become subject.

Rest of the World Regulation

For other countries outside of the EU, United Kingdom and the United States, such as countries in Eastern Europe, Latin America or
Asia,  the  requirements  governing  the  conduct  of  clinical  trials,  product  licensing,  pricing  and  reimbursement  vary  from  country  to  country.
Additionally, clinical trials must be conducted in accordance with cGCP requirements, the applicable regulatory requirements and the ethical
principles that have their origin in the Declaration of Helsinki. Failure to comply with applicable foreign laws and regulatory requirements may
result  in,  among  other  things,  fines,  suspension  or  withdrawal  of  regulatory  approvals,  product  recalls,  seizure  of  products  and  operating
restrictions.

Additional Laws and Regulations Governing International Operations

If we further expand our operations outside of the United States, we must dedicate additional resources to comply with numerous

laws and regulations in each jurisdiction in which we plan to operate, in addition to the FCPA

32

Table of Contents

as described above. For example, the UK Bribery Act of 2010 applies to companies that carry on all or part of their business in the UK, and
prohibits bribing another person or being bribed, bribing a foreign public official with the intent to influence and obtain or retain business or an
advantage, and failure by a commercial party to prevent bribery, including where the prohibited conduct or its effects occurred entirely outside
the UK.

Compliance  with  the  FCPA  and  anti-corruption  and  anti-bribery  laws  in  other  countries  is  expensive  and  difficult,  particularly  in
countries in which corruption is a recognized problem. In addition, the FCPA presents particular challenges in the pharmaceutical industry
because,  in  many  countries,  hospitals  are  operated  by  the  government  and  doctors  and  other  hospital  employees  are  considered  foreign
officials.  Certain  payments  to  hospitals  in  connection  with  clinical  trials  and  other  work  have  been  deemed  to  be  improper  payments  to
government officials and have led to FCPA enforcement actions.

Various laws, regulations and executive orders also restrict the use and dissemination outside of the United States, or the sharing
with certain non-U.S. nationals, of information classified for national security purposes, as well as certain products and technical data relating
to those products. If we expand our presence outside of the United States, it will require us to dedicate additional resources to comply with
these laws, and these laws may preclude us from developing, manufacturing or selling certain products and product candidates outside of
the United States, which could limit our growth potential and increase our development costs.

The failure to comply with laws governing international business practices may result in substantial civil and criminal penalties and
suspension or debarment from government contracting. The SEC also may suspend or bar issuers from trading securities on U.S. exchanges
for violations of the FCPA’s accounting provisions.

Coverage, Pricing and Reimbursement

In the United States and in foreign markets, sales of any products for which we receive regulatory approval for commercial sale will
depend, in part, on the extent to which third-party payors provide coverage and establish adequate reimbursement levels for such products.
In the United States, third-party payors include federal and state healthcare programs, private managed care providers, health insurers and
other organizations. Adequate coverage and reimbursement from governmental healthcare programs, such as Medicare and Medicaid in the
United States, and commercial payors are critical to new product acceptance.

Coverage  and  reimbursement  by  a  third-party  payor  may  depend  upon  a  number  of  factors,  including  the  third-party  payor’s

determination that use of a therapeutic is:

•

•

•

•

•

a covered benefit under its health plan;

safe, effective and medically necessary;

appropriate for the specific patient;

cost-effective; and

neither experimental nor investigational.

Coverage  may  also  be  more  limited  than  the  purposes  for  which  the  product  is  approved  by  the  FDA  or  comparable  foreign

regulatory authorities. Reimbursement may impact the demand for, or the price of, any product for which we obtain regulatory approval.

Third-party payors are increasingly challenging the price, examining the medical necessity and reviewing the cost-effectiveness of
medical products, therapies and services, in addition to questioning their safety and efficacy. Obtaining reimbursement for our products may
be particularly difficult because of the higher prices often associated with branded drugs and drugs administered under the supervision of a
physician.  We  may  need  to  conduct  expensive  pharmacoeconomic  studies  in  order  to  demonstrate  the  medical  necessity  and  cost-
effectiveness of our products. Obtaining coverage and reimbursement approval of a product from a government or other third-party payor is a
time-consuming and costly process that could require us to provide to each payor supporting scientific, clinical and cost-effectiveness data
for  the  use  of  our  product  on  a  payor-by-payor  basis,  with  no  assurance  that  coverage  and  adequate  reimbursement  will  be  obtained.  A
payor’s decision to provide coverage for a product does not imply that an adequate reimbursement rate will be approved. Adequate third-
party reimbursement may not be available to enable us to maintain price levels sufficient to realize an appropriate return on our investment in
product  development.  If  reimbursement  is  not  available  or  is  available  only  at  limited  levels,  we  may  not  be  able  to  successfully
commercialize any product candidate that we successfully develop.

Different pricing and reimbursement schemes exist in other countries. In the EU, governments influence the price of pharmaceutical
products through their pricing and reimbursement rules and control of national health care systems that fund a large part of the cost of those
products to consumers. Some EU Member States may approve a

33

Table of Contents

specific price for a product, or they may instead adopt a system of direct or indirect controls on the profitability of the company placing the
product on the market.

Some  jurisdictions  operate  positive  and  negative  list  systems  under  which  products  may  only  be  marketed  once  a  reimbursement
price  has  been  agreed.  In  addition,  to  obtain  reimbursement  or  pricing  approval,  some  of  these  countries  may  require  the  completion  of
studies  that  compare  the  cost  effectiveness  of  a  particular  product  candidate  to  currently  available  therapies.  This  Health  Technology
Assessment, or HTA, process is the procedure according to which the assessment of the public health impact, therapeutic impact and the
economic and societal impact of use of a given medicinal product in the national healthcare systems of the individual country is conducted.
The  outcome  of  HTA  regarding  specific  medicinal  products  will  often  influence  the  pricing  and  reimbursement  status  granted  to  these
medicinal products by the competent authorities of individual EU Member States. In December 2021, Regulation No 2021/2282 on Health
Technology Assessment, or HTA Regulation, was adopted. The HTA Regulation is intended to boost cooperation among EU Member States
in  assessing  health  technologies,  including  new  medicinal  products,  and  providing  the  basis  for  cooperation  at  EU  level  for  joint  clinical
assessments in these areas. When it enters into application in 2025, the HTA Regulation will be intended to harmonize the clinical benefit
assessment of HTA across the European Union. In light of the fact that the United Kingdom has left the EU, Regulation No 2021/2282 on
HTA will not apply in the United Kingdom. However, the MHRA is working with UK HTA bodies and other national organizations, such as the
Scottish  Medicines  Consortium,  or  SMC,  the  National  Institute  for  Health  and  Care  Excellence,  or  NICE,  and  the  All-Wales  Medicines
Strategy  Group,  to  introduce  new  pathways  supporting  innovative  approaches  to  the  safe,  timely  and  efficient  development  of  medicinal
products. Other member states allow companies to fix their own prices for medicines but monitor and control prescription volumes and issue
guidance to physicians to limit prescriptions. The downward pressure on health care costs has become intense. As a result, increasingly high
barriers are being erected to the entry of new products. In addition, in some countries, cross-border imports from low-priced markets exert a
commercial pressure on pricing within a country.

The  marketability  of  any  product  candidates  for  which  we  receive  regulatory  approval  for  commercial  sale  may  suffer  if  the
government  and  third-party  payors  fail  to  provide  adequate  coverage  and  reimbursement.  In  addition,  emphasis  on  managed  care,  the
increasing  influence  of  health  maintenance  organizations  and  additional  legislative  changes  in  the  United  States  have  increased,  and  we
expect  will  continue  to  increase,  the  pressure  on  healthcare  pricing.  The  downward  pressure  on  the  rise  in  healthcare  costs  in  general,
particularly  prescription  medicines,  medical  devices  and  surgical  procedures  and  other  treatments,  has  become  very  intense.  Coverage
policies and third-party reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained for
one  or  more  products  for  which  we  receive  regulatory  approval,  less  favorable  coverage  policies  and  reimbursement  rates  may  be
implemented in the future.

Before products become available to patients in the EEA, they are generally subject to decisions on pricing and reimbursement by
the  applicable  authorities  in  an  EEA  country.  Key  criteria  to  determine  the  reimbursement  status  and  pricing  of  a  product  may  include  the
product’s therapeutic value, medical need, safety and cost effectiveness. Obtaining pricing and reimbursement approval of a product from a
government  is  a  time-consuming  and  costly  process,  and  significant  uncertainty  exists  as  to  the  pricing  and  reimbursement  status  of  any
product candidates for which we may seek marketing approval in the EEA. Our ability to commercialize any such products successfully in the
EEA will depend, in part, on the outcome of these decisions.

In many EU Member States periodically review their reimbursement procedures for medicinal products, which could have an adverse
impact  on  reimbursement  status.  We  expect  that  legislators,  policymakers  and  healthcare  insurance  funds  in  the  EU  Member  States  will
continue to propose and implement cost-containing measures, such as lower maximum prices, lower or lack of reimbursement coverage and
incentives  to  use  cheaper,  usually  generic,  products  as  an  alternative  to  branded  products,  and/or  branded  products  available  through
parallel import to keep healthcare costs down.

Legislators,  policymakers  and  healthcare  insurance  funds  in  the  EU  and  the  UK  may  continue  to  propose  and  implement  cost-
containing measures to keep healthcare costs down. These measures could include limitations on the prices we would be able to charge for
product  candidates  that  we  may  successfully  develop  and  for  which  we  may  obtain  regulatory  approval  or  the  level  of  reimbursement
available  for  these  products  from  governmental  authorities  or  third-party  payors.  Further,  an  increasing  number  of  EU  and  other  foreign
countries use prices for medicinal products established in other countries as “reference prices” to help determine the price of the product in
their own territory. Consequently, a downward trend in prices of medicinal products in some countries could contribute to similar downward
trends elsewhere.

Healthcare Reform

In the United States and some foreign jurisdictions, there have been, and continue to be, several legislative and regulatory changes
and  proposed  changes  regarding  the  healthcare  system  that  could  prevent  or  delay  marketing  approval  of  product  candidates,  restrict  or
regulate post-approval activities and affect the ability to profitably sell product candidates for which marketing approval is obtained. Among
policy makers and payors in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with
the stated goals of containing healthcare costs, improving quality and/or expanding access. In the United States, the pharmaceutical industry
has been a particular focus of these efforts and has been significantly affected by major legislative initiatives.

The ultimate content, timing or effect of any healthcare reform legislation on the U.S. healthcare industry is unclear. For example, on
August 16, 2022, President Biden signed the Inflation Reduction Act of 2022, or the IRA, into law, which among other things, (1) directs the
U.S. Department of Health and Human Services, or HHS, to negotiate the price of certain single-source drugs and biologics covered under
Medicare  and  (2)  imposes  rebates  under  Medicare  Part  B  and  Medicare  Part  D  to  penalize  price  increases  that  outpace  inflation.  These
provisions will take effect progressively starting in fiscal year 2023. On August 29, 2023, HHS announced the list of the first ten drugs that will
be subject to price negotiations, although the Medicare drug price negotiation program is currently subject to legal challenges. It is unclear
how the IRA will be implemented but is likely to have a significant impact on the pharmaceutical industry.

Further,  in  March  2010,  the  ACA  was  signed  into  law  and  has  substantially  changed  healthcare  financing  and  delivery  by  both
governmental and private insurers. Among the ACA provisions of importance to the pharmaceutical and biotechnology industries are those
governing enrollment in federal healthcare programs, a new methodology by which rebates owed by manufacturers under the Medicaid Drug
Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted or injected and annual fees based on pharmaceutical
companies’ share of sales to federal healthcare programs.

There have been legal and political challenges to certain aspects of the ACA. For example, former President Trump signed several
executive orders and other directives designed to delay, circumvent or loosen certain requirements mandated by the ACA. On June 17, 2021,
the  U.S.  Supreme  Court  dismissed  a  challenge  on  procedural  grounds  that  argued  the  ACA  is  unconstitutional  in  its  entirety  because  the
“individual  mandate”  was  repealed  by  Congress.  However,  the  ACA  may  be  subject  to  judicial  or  Congressional  challenges  in  the  future.
Additionally,  on  January  28,  2021,  President  Biden  issued  an  executive  order  instructing  certain  governmental  agencies  to  review  and
reconsider  their  existing  policies  and  rules  that  limit  access  to  healthcare,  including  among  others,  reexamining  Medicaid  demonstration
projects  and  waiver  programs  that  include  work  requirements,  and  policies  that  create  unnecessary  barriers  to  obtaining  access  to  health
insurance  coverage  through  Medicaid  or  the  ACA.  The  IRA,  among  other  things,  extends  enhanced  subsidies  for  individuals  purchasing
health insurance coverage in ACA marketplaces through plan year 2025 and eliminates the “donut hole” under the Medicare Part D program
beginning in 2025 by significantly lowering the beneficiary maximum out-of-pocket cost through a newly established manufacturer discount
program.

We anticipate that the ACA, if substantially maintained in its current form, will continue to result in additional downward pressure on
coverage  and  the  price  that  we  receive  for  any  approved  product,  and  could  harm  our  business.  Any  reduction  in  reimbursement  from
Medicare  and  other  government  programs  may  result  in  a  similar  reduction  in  payments  from  private  payors.  The  implementation  of  cost
containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability or commercialize
our products.

Further legislation or regulation could be passed that could harm our business, financial condition and results of operations. Other
legislative changes have been proposed and adopted since the ACA was enacted. Aggregate reductions to Medicare payments to providers
of up to 2% per fiscal year, which went into effect beginning on April 1, 2013, will stay in effect through 2032 unless additional Congressional
action is taken.

Additionally, there has been increasing legislative and enforcement interest in the United States with respect to specialty drug pricing
practices. Specifically, there have been several U.S. congressional inquiries, presidential executive orders and proposed and enacted federal
legislation designed to, among other things, bring more transparency to drug pricing, reduce the cost of prescription drugs under Medicare,
review the relationship between pricing and manufacturer-patient programs and reform government program reimbursement methodologies
for  drugs.  For  example,  in  July  2021,  the  Biden  administration  released  an  executive  order,  “Promoting  Competition  in  the  American
Economy,” with multiple provisions aimed at prescription drugs. In response to President Biden’s executive order, on September 9, 2021, the
United  States  Department  of  Health  and  Human  Services,  or  HHS,  released  a  Comprehensive  Plan  for  Addressing  High  Drug  Prices  that
outlines principles for drug pricing reform and

35

Table of Contents

sets  out  a  variety  of  potential  legislative  policies  that  Congress  could  pursue  as  well  as  potential  administrative  actions  HHS  can  take  to
advance  these  principles.  Further,  the  Biden  administration  released  an  additional  executive  order  on  October  14,  2022,  directing  HHS  to
submit a report on how the Center for Medicare and Medicaid Innovation can be further leveraged to test new models for lowering drug costs
for  Medicare  and  Medicaid  beneficiaries.  In  response  to  the  Biden  administration’s  October  2022  executive  order,  on  February  14,  2023,
HHS released a report outlining three new models for testing by the Centers for Medicare & Medicaid Services, or CMS, Innovation Center
which will be evaluated on their ability to lower the cost of drugs, promote accessibility, and improve quality of care. It is unclear whether the
models will be utilized in any health reform measures in the future. Further, on December 7, 2023, the Biden administration announced an
initiative to control the price of prescription drugs through the use of march-in rights under the Bayh-Dole Act. On December 8, 2023, the
National  Institute  of  Standards  and  Technology  published  for  comment  a  Draft  Interagency  Guidance  Framework  for  Considering  the
Exercise of March-In Rights which for the first time includes the price of a product as one factor an agency can use when deciding to exercise
march-in rights. While march-in rights have not previously been exercised, it is uncertain if that will continue under the new framework. It is
unclear whether this executive order or similar policy initiatives will be implemented in the future. Individual states in the United States have
also  become  increasingly  active  in  passing  legislation  and  implementing  regulations  designed  to  control  pharmaceutical  product  pricing,
including  price  or  patient  reimbursement  constraints,  discounts,  restrictions  on  certain  product  access  and  marketing  cost  disclosure  and
transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. For example, on
January  5,  2024,  the  FDA  approved  Florida’s  Section  804  Importation  Program,  or  SIP,  proposal  to  import  certain  drugs  from  Canada  for
specific state healthcare programs. It is unclear how this program will be implemented, including which drugs will be chosen, and whether it
will be subject to legal challenges in the United States or Canada. Other states have also submitted SIP proposals that are pending review by
the FDA. Any such approved importation plans, when implemented, may result in lower drug prices for products covered by those programs.

Human Capital

Our team of talented scientists and industry professionals is the foundation of our company and fuels our historical and prospective
achievements  for  patients.  We  consider  the  intellectual  capital  of  our  employees  to  be  an  essential  driver  of  our  business  and  key  to  our
future opportunities. As of December 31, 2023, we had 138 employees, of which approximately 97 (70%) were engaged in R&D activities, 52
hold Ph.D. and/or M.D. degrees and an additional 31 hold a master's or other postgraduate degree. Every NGM Bio team member plays a
vital  role  in  furthering  our  goals  and  impacting  our  progress  towards  fully  realizing  our  mission  to  develop  transformative  therapies  for
patients.

To  succeed  in  our  mission,  we  must  attract,  recruit,  retain,  develop  and  motivate  qualified  clinical,  nonclinical,  scientific,
manufacturing,  regulatory,  management  and  other  personnel  needed  to  support  our  business  and  operations.  We  recruit  for  talent  in  the
biotechnology and pharmaceutical industry in the San Francisco Bay Area, which is in one of the most competitive and highest cost labor
markets  in  the  United  States  and  periodically  experiences  higher  turnover  rates  than  other  industries.  We  maintain  a  comprehensive
dashboard of measurements, including recruitment productivity, diversity, equity and inclusion metrics, employee engagement scores, total
rewards benchmarking, participation rates and satisfaction scores for internal training, turnover rates and exit interview results, to guide our
human capital management efforts.

We believe that we can best address competitive challenges by enhancing the reputation of NGM Bio as a great place to work, which
includes  nurturing  our  workplace  culture,  providing  competitive  compensation  and  benefits  programs  and  supporting  employee  career
development and related management training. To that end, we continue to invest resources and energy into being an employer of choice –
attracting and engaging individuals who are innovative, curious, driven, diligent, collaborative and of the highest integrity and ethics. Some of
our key efforts in this area and management of our human capital assets generally are described here.

Compensation and Benefits

Our compensation philosophy is to provide pay and benefits that are competitive in the biotechnology and pharmaceutical industry
where  we  compete  for  talent.  We  monitor  our  compensation  programs  closely  and  review  them  throughout  the  year  to  provide  what  we
consider  a  very  competitive  mix  of  compensation  and  health,  welfare  and  retirement  benefits  for  all  our  employees.  Our  compensation
package  for  all  employees  includes  market-competitive  base  salaries,  eligibility  for  annual  performance  bonuses  and  equity  grants.  Our
benefits programs include company-sponsored medical, dental and vision health care coverage, life and AD&D insurance, a 401(k) plan with
a matching employer contribution, paid time off and family leave and an employee stock purchase plan, among others benefits. Every year,
we undertake a detailed review of our compensation by position and level and

36

Table of Contents

make adjustments necessary to ensure that we continue to provide competitive compensation. Our hiring practices and annual compensation
reviews are designed to ensure fairness in pay equity across gender and ethnicity among similar roles and responsibilities throughout our
organization,  after  accounting  for  legitimate  business  factors  that  can  explain  differences,  such  as  performance,  time  at  grade  level,
education and tenure. To comply with the California’s Pay Transparency law (SB 1162), beginning January 1, 2023, we publish pay ranges in
all job postings and we proactively provide existing employees with the salary range for their positions. In addition, our efforts extend beyond
pay equity to include fairness in gender and ethnic representation at all levels in the organization.

Diversity, Equity and Inclusion

We believe that a diverse, equitable and inclusive workplace is key to our long-term success. As of December 31, 2023, NGM Bio
employed 79 women (57%) and 59 men (43%), and 85 (62%) of our employees are non-white, including 15 (11%) that are from traditionally
underrepresented groups. Our leadership, including employees at or above the vice president level and members of our board of directors,
includes 53% women and 26% who are non-white. To champion our efforts in this area, a cross-functional team of employees continues to
drive  our  diversity,  equity  and  inclusion  initiatives  that  have  focused  on  awareness  and  understanding;  diverse  candidate  pipelines;
community outreach; advocacy and career advancement; and business impact. Our efforts, which began in 2020 with a focus on anti-Black
racism,  have  included  mandatory  unconscious  bias  and  discrimination  training,  an  employee-led  diversity  page  on  our  intranet  updated
monthly  with  fresh  content,  voluntary  participation  in  a  program  to  encourage  allyship,  guest  speaker  programs  on  diversity,  equity  and
inclusion, or DEI, topics, and conducting a survey to understand employee sentiment around race-related issues to establish a baseline for
tracking future progress. We implemented an internship program targeted to students from underrepresented minorities and adopted specific
quantitative efforts to provide NGM Bio with a diverse candidate pipeline and more diverse interview panels. In addition to internal efforts, our
research employees volunteer to teach elementary school students various topics in biology.

In 2022, we engaged an external consultant with expertise in DEI to help conduct an assessment to understand where improvements
could be made in our culture to drive equitable outcomes and foster an inclusive environment, with a particular focus on women scientists.
The assessment included cross-organizational interviews, focus group discussions, a detailed review of our policies, programs and business
norms, an all-employee inclusion survey and a review of organizational diversity metrics to determine what are the barriers to success and
advancement of women and underrepresented groups. The project identified three areas of action that are being shared across NGM Bio,
and we began implementing the recommendations in 2023, conducting inclusive leadership training and developing inclusive meeting norms.
In addition, we support an employee-led employee resource group, N-GAGE (NGM Gathers to Advance Gender Equity). Since its inception,
N-GAGE  has  supported  the  DEI  assessment,  created  community  spaces  for  engagement  and  discussions  on  current  topics
disproportionately affecting women, and incubated a company-wide mentorship and professional enrichment program.

Communication and Engagement

We  believe  that  part  of  what  sets  NGM  Bio  apart  from  other  companies  is  our  culture  and  our  focus  on  providing  timely  and
transparent communications and creating a strong sense of belonging and inclusiveness. We engage in many traditions and celebrations that
contribute  to  what  makes  NGM  Bio  a  special  place  to  work:  monthly  themed  happy  hours;  weekly  group  lunch  programs,  often  with
employee-led  lunch-and-learns  with  scientific  and  other  updates  of  interest;  quarterly  all-hands'  meetings;  regular  coffee  chats  or  other
gatherings  for  small  groups  with  our  CEO  and  other  members  of  senior  management;  and  events  including  a  summer  family  picnic,
Thanksgiving potluck and holiday white elephant party, among many others. We survey our employees each year to measure their level of
engagement at NGM Bio. These surveys provide rich feedback each year that helps us to continue to grow our culture and strive to make
NGM Bio a great place to work.

Health, Wellness and Safety

We continue to offer services to promote our employees' whole health and wellness, including an on-site gym, external support from

our employee assistance program and mental wellness and health advocacy services.

None of our employees is subject to a collective bargaining agreement or represented by a trade or labor union. We consider our

relations with our employees to be good.

Item 1A.    Risk Factors.

An  investment  in  our  common  stock  involves  a  high  degree  of  risk.  You  should  carefully  consider  the  risks  and  uncertainties
described below before deciding whether to make an investment decision with respect to our common stock. You should also refer to the
other information contained in this Annual Report on Form 10-K, or Annual Report, including in Part II, Item 7, “Management’s Discussion
and Analysis of Financial Condition and Results of Operations” and in our consolidated financial statements and related notes, as well as our
other filings with the U.S. Securities and Exchange Commission, or SEC. Our business, financial condition, results of operations, stock price
and prospects could be materially and adversely affected by any of these risks or uncertainties. In any such case, the trading price of our
common stock could decline, and you could lose all or part of your investment. We caution you that the risks, uncertainties and other factors
referred to below and elsewhere in this Annual Report may not contain all of the risks, uncertainties and other factors that may affect our
future  results  and  operations.  Additional  risks  and  uncertainties  not  presently  known  to  us  or  that  we  currently  deem  immaterial  may  also
impair  our  business  operations  and  the  market  price  of  our  common  stock.  Moreover,  new  risks  will  emerge  from  time  to  time.  It  is  not
possible for our management to predict all risks.

On February 25, 2024, we entered into an Agreement and Plan of Merger, or the Merger Agreement, with Atlas Neon Parent, Inc., or
Parent, and Atlas Neon Merger Sub, Inc., a wholly-owned subsidiary of Parent, or Merger Sub. The Merger Agreement provides for, among
other  things,  (i)  the  acquisition  of  the  Company  by  Parent  through  a  cash  tender  offer,  or  the  Offer,  by  Merger  Sub  for  each  issued  and
outstanding share of our common stock for $1.55 per share, or the Offer Price, and (ii) the merger of Merger Sub with and into the Company,
or the Merger, with the Company surviving the Merger. The Merger Agreement, the Offer and the Merger are described in more detail under
“Pending Transactions Contemplated by the Merger Agreement” in Part I, Item 1 of this Annual Report.

If  the  Merger  is  effected,  our  common  stock  will  be  delisted  from  The  Nasdaq  Global  Select  Market  and  we  will  be  privately  held.
During the pendency of the Merger, we may be subject to certain risks and uncertainties as more fully described below under the heading
"Risks Related to the Offer and the Merger." If the Merger is not consummated for any reason, we will remain subject to the other risks and
uncertainties described below.

Risks Related to the Offer and the Merger

The Offer and the Merger are subject to a number of conditions beyond our control. Failure to complete the Offer and the Merger
within  the  expected  time  frame,  or  at  all,  could  have  a  material  adverse  effect  on  our  business,  operating  results,  financial
condition and our stock price.

The Offer and the Merger are subject to a number of conditions beyond our control, including: (i) that the number of shares of our
common stock validly tendered and not validly withdrawn, represents at least a majority of our common stock then outstanding owned by the
Unaffiliated  Stockholders  as  of  the  expiration  of  the  Offer;  (ii)  the  accuracy  of  our  representations  and  warranties  contained  in  the  Merger
Agreement (subject to certain exceptions and qualifications described in the Merger Agreement and except, generally, for any inaccuracies
that have not had a Company Material Adverse Effect (as defined in the Merger Agreement)); (iii) our performance in all material respects of
its obligations under the Merger Agreement and (iv) the other conditions set forth in Exhibit A to the Merger Agreement. The obligations of
Parent and Merger Sub to consummate the Offer and the Merger under the Merger Agreement are not subject to a financing condition.

We cannot predict whether or when the conditions to the Offer will be satisfied. If one or more of the conditions are not satisfied, and
as  a  result,  we  do  not  complete  the  Offer  and  the  Merger,  we  would  remain  liable  for  significant  transaction  costs,  and  the  focus  of  our
management would have been diverted from advancing our three key development opportunities, in each case without realizing any benefits
of the Offer and the Merger. Any disruptions to our business resulting from the announcement and pendency of the Offer and the Merger,
including any adverse changes in our relationships with our business partners, suppliers and employees, could continue or accelerate in the
event that we fail to consummate the Offer and the Merger.

Our stock price may also fluctuate significantly based on announcements by Parent, other third parties, or us regarding the Offer and
the Merger or based on market perceptions of the likelihood of the satisfaction of the Minimum Tender Condition (as defined in the Merger
Agreement)  or  other  conditions  to  the  consummation  of  the  Offer  and  the  Merger  outside  of  our  control,  such  as  a  governmental  entity
enacting a legal restraint or prohibition that that prevents or prohibits the Offer or the Merger. Such announcements may lead to perceptions
in the market that the Offer and the Merger may not be completed, which could cause our stock price to fluctuate or decline.

39

Table of Contents

If we do not consummate the Offer and the Merger, our stock price may decline significantly from the current market price, which

may reflect a market assumption that the Offer and the Merger will be consummated.

The occurrence of any of these events could have a material adverse effect on our business, operating results and financial condition

and could cause a decline in our stock price.

The Merger Agreement contains provisions that could discourage a potential competing acquirer.

The  Merger  Agreement  provides  that,  upon  the  terms  and  subject  to  the  conditions  thereof,  NGM  and  its  representatives  cannot
directly or indirectly solicit, initiate or knowingly encourage or knowingly facilitate discussions with third parties regarding other proposals to
acquire or combine with NGM, and we are subject to restrictions on our ability to respond to any such proposal. In the event that we receive
an acquisition proposal from a third party, we must notify Parent of such proposal and negotiate in good faith with Parent prior to terminating
the  Merger  Agreement  or  effecting  a  change  in  the  recommendation  of  our  Board  and  the  Special  Committee  of  the  Board  to  our
stockholders  with  respect  to  the  Offer  and  Merger.  The  Merger  Agreement  also  contains  certain  termination  rights  for  Parent  and  us  and
further provides that, upon termination of the Merger Agreement under specified circumstances, including certain terminations in connection
with an alternative business combination transaction as permitted by the terms of the Merger Agreement, we will be required to pay Parent a
termination fee of $2.0 million. These provisions could discourage a potential third-party acquirer that might have an interest in acquiring all
or a significant portion of our common stock from considering or proposing that acquisition, even if it were prepared to pay consideration with
a higher per share cash or market value than the Offer Price proposed to be received or realized in the transaction. These provisions also
might result in a potential third-party acquirer proposing to pay a lower price to our stockholders than it might otherwise have proposed to pay
due to the added expense of the termination fee that may become payable in certain circumstances. If the Merger Agreement is terminated
and  we  determine  to  seek  another  business  combination,  we  may  not  be  able  to  negotiate  a  transaction  with  another  party  on  terms
comparable to, or better than, the terms of the Offer and Merger.

While the Offer and the Merger are pending, we are subject to business uncertainties and contractual restrictions that limit our
ability to pursue financing or BD Arrangements and could disrupt our business, and the Offer and the Merger may impair our
ability to attract and retain qualified employees or retain and maintain relationships with our suppliers and other business
partners.

Whether or not the Offer and the Merger are consummated, the Offer and the Merger may disrupt our current plans and operations,
which could have an adverse effect on our business and financial condition. The pendency of the Offer and the Merger will also divert much
of  management’s  attention  and  our  resources  from  addressing  ongoing  financing  needs  and  may  divert  management's  attention  and
resources  from  our  ongoing  business  and  operations  and  our  employees.  In  addition,  the  pending  Offer  and  the  Merger,  as  well  as  the
related  prior  public  announcement  by  The  Column  Group,  LP  of  its  intent  to  explore  and  evaluate  a  potential  acquisition  of  the  Company,
makes  it  more  difficult  to  retain  qualified  employees  while  the  Offer  and  the  Merger  are  pending  or  in  the  event  that  we  are  unable  to
consummate the Offer or the Merger within the expected time frames or at all. If key personnel depart because of such uncertainties, our
business and results of operations may be adversely affected.

In  addition,  pending  consummation  of  the  Offer  and  the  Merger,  the  Merger  Agreement  generally  requires  us  to  operate  in  the
ordinary  course  of  business  consistent  with  past  practice  and  restricts  us  from  taking  certain  actions  with  respect  to  our  business  and
financial  affairs  without  Parent’s  consent.  Such  restrictions  will  be  in  place  until  either  the  Offer  and  the  Merger  are  consummated  or  the
Merger  Agreement  is  terminated.  These  restrictions  could  restrict  our  ability  to  pursue  or  prevent  us  from  pursuing  attractive  business  or
fundraising opportunities (if any) that arise prior to the consummation of the Offer and the Merger. For example, our ability to raise additional
capital  through  the  issuance  of  equity  securities,  incur  indebtedness  or  pursue  collaboration,  out-licensing,  partnership  or  other  business
development arrangements, or BD Arrangements, are generally restricted without Parent’s consent during the pendency of the Offer and the
Merger. For these and other reasons, the pendency of the Offer and the Merger could adversely affect our business, operating results and
financial condition.

As a clinical stage biotechnology company, our operations consume substantial amounts of cash, and we need significant additional
capital to finance our operations and pursue our strategy. During the pendency of the Merger, restrictions on our ability to deploy our cash
resources  or  raise  additional  cash  could  impede  the  progress  of  our  clinical  programs.  These  restrictions  will  remain  in  place  until  the
consummation or earlier termination of the Merger Agreement. As a result, we may be subject to these restrictions until June 15, 2024, which
is the date after which we or Parent may terminate the Merger Agreement if the Merger has not already occurred, or later, should we and the
Parent choose not to terminate the Merger Agreement at such time. In addition, if the Merger is not consummated, we may face increased
difficulties raising capital and may need to significantly delay, scale back or

40

Table of Contents

discontinue development of, or abandon some or all of, our product candidates, or scale back or discontinue our discovery research efforts.

Stockholder  litigation  could  prevent  or  delay  the  consummation  of  the  Offer  and  the  Merger  or  otherwise  negatively  impact  our
business, operating results and financial condition.

We may incur additional costs in connection with the defense or settlement of any future stockholder litigation in connection with the
Offer  and  the  Merger.  Any  such  future  litigation  may  adversely  affect  our  ability  to  complete  the  Offer  and  the  Merger.  We  could  incur
significant  costs  in  connection  with  any  such  litigation,  including  costs  associated  with  the  indemnification  of  our  directors  and  officers.
Furthermore,  one  of  the  conditions  to  the  consummation  of  the  Offer  and  the  Merger  is  the  Legal  Restraints  condition  (as  defined  in  the
Merger  Agreement),  such  as,  for  example,  if  there  is  a  legal  prohibition  imposed  by  a  governmental  entity  preventing  or  prohibiting  the
consummation  of  the  Merger  then  in  effect.  Consequently,  if  a  plaintiff  were  to  secure  injunctive  or  other  relief  prohibiting,  delaying  or
otherwise adversely affecting our ability to complete the consummation of the Offer and the Merger, then such injunctive or other relief may
prevent the consummation of the Offer or the Merger within the expected time frames or at all.

We  may  become  involved  in  securities  class  action  litigation  due  to  the  Offer  and  the  Merger  that  could  divert  management’s
attention and harm our business, and adversely affect our ability to consummate the Offer and the Merger within the expected time
frame or at all.

In  the  past,  securities  class  action  litigation  has  often  followed  certain  significant  business  transactions,  such  as  the  sale  of  a
company or announcement of any other strategic transaction, or the announcement of negative events, such as negative results from clinical
trials. These events may also result in investigations by the SEC. We may be subject to such litigation or investigation even if no wrongdoing
has occurred. Litigation and investigations are usually expensive and divert management’s attention and resources, which could adversely
affect our business and cash resources and our ability to consummate the Offer and the Merger within the expected time frame or at all.

Our executive officers and directors may have interests in the Offer and the Merger that are different from, or in addition to, those
of our stockholders generally.

Our executive officers and directors may have interests in the Offer and the Merger that are different from, or are in addition to, those
of our stockholders generally, including the acceleration of equity awards in connection with the Merger and potential severance payments.
Such  interests  of  our  directors  and  executive  officers  are  set  forth  in  further  detail  in  the  Schedule  14D-9  filed  by  NGM  with  the  SEC  on
March 8, 2024.

In  particular,  David  V.  Goeddel,  Ph.D.  and  William  J.  Rieflin  entered  into  the  Rollover  Agreement  (as  defined  in  the  Merger
Agreement)  on  the  date  of  the  Merger  Agreement,  and  David  J.  Woodhouse,  Ph.D.  entered  into  a  joinder  to  the  Rollover  Agreement  on
March 6, 2024. Dr. Goeddel is a Managing Partner of The Column Group and our lead independent director. Mr. Rieflin is the Non-executive
Chairman of our board of directors. Dr. Woodhouse is our Chief Executive Officer and a member of our board of directors. In addition, Roger
M. Perlmutter, M.D., Ph.D., a member of our board of directors, is a Science Partner with The Column Group. The interests of Dr. Goeddel,
Dr. Perlmutter, Mr. Rieflin and Dr. Woodhouse may not coincide with the interests of our other stockholders, particularly as it relates to The
Column Group, the Offer and the Merger.

We have incurred, and will continue to incur, direct and indirect costs as a result of the Offer and the Merger.

We  have  incurred,  and  will  continue  to  incur,  significant  costs  and  expenses,  including  fees  for  professional  services  and  other
transaction costs, in connection with the Offer and the Merger, including costs that we may not currently expect. We must pay substantially all
of  these  costs  and  expenses  whether  or  not  the  transaction  is  completed.  If  the  Merger  Agreement  is  terminated  under  specified
circumstances,  including  certain  terminations  in  connection  with  a  Superior  Company  Proposal  transaction  (as  defined  in  the  Merger
Agreement), we will be required to pay to Parent a termination fee equal to $2.0 million.

Risks Related to Our Financial Condition and Capital Needs

We have incurred net losses every year since our inception and have no meaningful source of revenue. We expect to continue to
incur significant operating losses and may never become profitable.

We have no products approved for commercial sale and have not generated any revenue from product sales to date. As a result, we

are not profitable and have incurred losses in each year since commencing

41

Table of Contents

operations. Our net losses were $142.4 million, $162.7 million and $120.3 million for the years ended December 31, 2023, 2022 and 2021,
respectively. As of December 31, 2023, we had an accumulated deficit of $724.0 million.

We expect to continue to incur significant research and development, or R&D, and other expenses related to our ongoing operations
for  the  foreseeable  future,  particularly  to  fund  R&D  of,  and,  if  warranted,  to  seek  regulatory  approvals  for,  our  product  candidates.  We
incurred  substantial  net  operating  losses  in  2023  and  expect  to  continue  to  incur  significant  operating  losses  in  2024  and  over  the  next
several  years  as  our  research,  development,  manufacturing,  preclinical  studies,  clinical  trial  and  related  activities  continue.  We  expect  our
accumulated deficit will also increase in future periods. The size of our future net losses will depend, in part, on the amount of our expenses
and our ability to generate revenue. In this regard, we will receive minimal funding from Merck Sharp & Dohme LLC, or Merck, through the
first half of 2024 under the amended and restated research collaboration, product development and license agreement we entered into with
Merck on June 30, 2021, or the Amended Collaboration Agreement, and we do not expect any funding thereafter from Merck. Accordingly,
the Amended Collaboration Agreement is no longer a source of any meaningful revenue for us and we otherwise have no alternative sources
of revenue in place.

Our prior losses and expected future losses have had and will continue to have an adverse effect on our stockholders’ equity and

working capital.

In addition, we will not be able to generate product revenue unless and until one of our product candidates successfully completes
clinical  trials,  receives  regulatory  approval  and  is  successfully  commercialized.  As  our  most  advanced  product  candidate  within  our  key
priorities for clinical development is only in Phase 2 development, we do not expect to receive product revenue from our product candidates
for a number of years, if ever.

Our ability to generate any product revenue from our current or future product candidates also depends on a number of additional

factors, including our ability or the ability of any potential future third-party partner to:

•

•

•

•

•

•

•

•

successfully complete research and clinical development of current and future product candidates and obtain regulatory approval for
those product candidates;

establish  and  maintain  supply  and  manufacturing  relationships  with  third  parties,  and  ensure  adequate,  scaled  up  and  legally
compliant manufacturing of bulk drug substances and drug products to maintain sufficient supply;

launch and commercialize any product candidates for which marketing approval is obtained, if any, and, if launched independently by
us without a partner, successfully establish a sales force and marketing and distribution infrastructure;

demonstrate the necessary safety data (and, if accelerated approval is obtained, verify the clinical benefit) post-approval to ensure
continued regulatory approval;

obtain  coverage  and  adequate  product  reimbursement  from  third-party  payors,  including  government  payors,  for  any  approved
products;

achieve market acceptance for any approved products;

establish, maintain, protect and enforce our intellectual property rights; and

attract, hire and retain qualified personnel.

Because  of  the  numerous  risks  and  uncertainties  associated  with  pharmaceutical  product  development,  including  that  our  product
candidates may not advance through development or be approved for commercial sale, we are unable to predict if or when we will generate
product revenue or achieve or maintain profitability.

Even  if  we  successfully  complete  development  and  regulatory  processes  for  any  product  candidates  that  we  take  forward,  we
anticipate incurring significant costs associated with launching and commercializing any approved products. If we fail to become profitable or
do not sustain profitability on a continuing basis, we may be unable to continue our operations at planned levels and be forced to reduce or
cease our operations.

We have minimal committed external funding for our development efforts and will need to rely on our own financial resources and
our ability to raise additional capital in order to further our development efforts.

We do not have any committed external source of funds, other than pursuant to the Amended Collaboration Agreement with Merck.
Under the Amended Collaboration Agreement, the research program term for certain minimal cardiovascular or metabolic-, or CVM-, related
programs will continue through March 31, 2024, unless the parties mutually agree to extend the research program term through March 31,
2026, in which case Merck would provide up to a total of $20.0 million in R&D funding during the additional two years of the CVM program
research

42

Table of Contents

program term. We do not expect the research program term will be extended. We expect to receive minimal funding from Merck in the first
half of 2024 and we do not expect any funding at all from Merck thereafter.

Other than our Amended Collaboration Agreement with Merck, we are not party to any agreements that could provide us with future
revenue. Accordingly, we will need to devote a substantial amount of our own financial resources to our R&D programs. As a result, in order
to advance our current and potential future product candidates through development and to regulatory approval and commercialization, we
need to raise significant additional capital and/or we will need to enter into BD Arrangements to obtain funding or other resources for one or
more of our wholly-owned programs. Neither may be possible and, as a result, we may need to significantly delay, scale back or discontinue
development of or abandon some or all of our product candidates, or scale back or discontinue our discovery research efforts, any of which
could have a material adverse effect on our business, operating results and prospects, or we may be required to cease operations altogether.
For example, we will need to raise significant additional capital in order to conduct any potential registrational trial of aldafermin in primary
sclerosing  cholangitis,  or  PSC.  In  addition,  clinical  development  of  NGM707  beyond  completing  the  Phase  1  Part  1b  cohort,  including
initiating additional cohorts, which may include MSS CRC patients, will require us to obtain the additional capital necessary to conduct such
development. Moreover, further development of certain of our product candidates, such as NGM438, NGM831, NGM621 and NGM313, is
dependent  on  our  ability  to  secure  future  BD  Arrangements  and,  in  the  absence  of  such  BD  Arrangements,  we  are  unlikely  to  advance
development  of  such  product  candidates  unless  our  portfolio  prioritization  changes  and  we  are  able  to  secure  the  additional  capital
necessary to fund such development.

We  need  significant  additional  capital  to  proceed  with  development  and  commercialization  of  our  current  and  potential  future
product candidates and our other operations. We may not be able to access sufficient capital on acceptable terms, if at all, and, as
a  result,  we  may  need  to  significantly  delay,  scale  back  or  discontinue  development  of  or  abandon  some  or  all  of  our  product
candidates, or scale back or discontinue our discovery research efforts, any of which could have a material adverse effect on our
business, operating results and prospects, or we may be required to cease operations altogether.

Our operations have consumed substantial amounts of cash since inception, and we need substantial additional capital to finance
our  operations  and  pursue  our  strategy,  both  in  the  short  and  the  long  term,  and  the  amount  of  funding  we  will  need  depends  on  many
factors, including:

•

•

•

•

•

the  initiation,  progress,  timing,  delays,  costs  and  results  of  preclinical  studies  and  clinical  trials  for  our  current  and  future  product
candidates;

the outcome, timing and cost of seeking and obtaining regulatory approvals from the United States Food and Drug Administration, or
FDA, and comparable foreign health authorities, including the potential for such authorities to require that we perform more studies
than those that we currently expect or to change their requirements on studies that had previously been agreed to;

the cost to establish, maintain, expand, enforce and defend the scope of our intellectual property portfolio, including the amount and
timing  of  any  payments  we  may  be  required  to  make,  or  that  we  may  receive,  in  connection  with  licensing,  preparing,  filing,
prosecuting, defending and enforcing any patents or other intellectual property rights;

the cost and timing of selecting, auditing and potentially validating a manufacturing site for later-stage clinical and commercial-scale
manufacturing;

the effect of products that may compete with our product candidates or other market developments;

• market acceptance of any approved product candidates, including product pricing and product reimbursement by third-party payors;

• whether  Merck  exercises  its  option  to  license  any  preclinical  candidates  from  our  CVM-related  programs  at  the  license  option
exercise point as specified in the Amended Collaboration Agreement for each such candidate, which we do not expect Merck to do;

• whether  Merck  terminates  the  research  program  term  of  the  collaboration  under  pre-specified  circumstances  set  forth  in  the
Amended Collaboration Agreement or terminates any future licensed program, such as Merck's decision to terminate its license for
NGM313 and its related compounds;

•

•

the cost of potentially acquiring, licensing or investing in additional businesses, products, product candidates and technologies; and

the  cost  of  establishing  sales,  marketing  and  distribution  capabilities  for  any  of  our  product  candidates  for  which  we  may  receive
regulatory approval and that we determine to commercialize ourselves or in collaboration with partners.

Table of Contents

At December 31, 2023, we had $144.2 million in cash, cash equivalents and short-term marketable securities. We believe that our
existing cash, cash equivalents and short-term marketable securities will be sufficient to fund our operations for at least one year from the
date this Annual Report is filed. We have based these estimates on plans and assumptions that may prove to be insufficient or inaccurate
(for example, with respect to anticipated costs, timing or success of certain activities), and we could utilize our available capital resources
sooner than we currently expect. These estimates do not include entering into BD Arrangements or receiving funds through debt or equity
financing activities and, as a result, unless we significantly lower our use of cash, we may no longer have sufficient cash, cash equivalents
and short-term marketable securities to fund our operations for more than one year at the end of future reporting periods. In addition, our
forecast of the time period through which our financial resources will be adequate to support our operations is a forward-looking statement
that  involves  risks  and  uncertainties,  and  actual  results  could  vary  materially  as  a  result  of  a  number  of  factors,  including  the  factors
discussed elsewhere in this “Risk Factors” section.

Additionally, in July 2022, we entered into an operating lease agreement, or the 2024 Lease Agreement, for our existing corporate
office and laboratory space at 333 Oyster Point Boulevard, South San Francisco, California. The initial term of the 2024 Lease Agreement
commenced on January 1, 2024 and expires on December 31, 2033. We do not expect to fully occupy our existing space for the foreseeable
future, which could negatively impact our financial results given the fixed costs associated with the lease.

On  June  7,  2023,  we  entered  into  Amendment  No.  1,  or  the  Amendment,  to  the  Open  Market  Sales  Agreement

,  or  the  Sales
Agreement,  with  Jefferies  LLC,  or  Jefferies,  and  we  refer  to  the  Sales  Agreement  as  amended  as  the  Amended  Sales  Agreement.  In
connection  with  the  Amendment,  we  filed  a  new  shelf  registration  statement  on  Form  S-3  which  the  SEC  declared  effective  on  August  4,
2023. The Amended Sales Agreement provides for the issuance and sales of shares of our common stock having an aggregate offering price
of up to $100.0 million through or to Jefferies.

SM

We  plan  to  finance  our  future  cash  needs  through  public  or  private  equity  or  debt  offerings,  including  under  the  Amended  Sales
Agreement,  BD  Arrangements  or  a  combination  of  these  potential  financing  sources.  Additional  capital  may  not  be  available  in  sufficient
amounts,  on  reasonable  terms  or  when  we  need  it,  if  at  all.  The  global  economy,  including  credit  and  financial  markets,  has  experienced
extreme  volatility  and  disruptions,  including,  among  other  things,  severely  diminished  liquidity  and  credit  availability,  declines  in  economic
growth, supply chain shortages and disruptions, increases in inflation rates, elevated interest rates and uncertainty about economic stability.
Increased inflation may result in increased operating costs (including labor costs) and may affect our operating budgets. In addition, the U.S.
Federal Reserve has raised, and may further raise, interest rates in response to concerns about inflation. Elevated interest rates, especially if
coupled with reduced government spending and volatility in financial markets, may further increase economic uncertainty and heighten these
risks. Additionally, public health crises and ongoing global geopolitical conflicts have created extreme volatility in the global capital markets
and are expected to have further global economic consequences, including disruptions of the global supply chain and energy markets.

Moreover, the closures of Silicon Valley Bank, or SVB, and other banks in early 2023 have resulted in broader financial institution
liquidity risk and concerns. Although we incurred no losses as a result of the closure of SVB or other banks, future adverse developments
with respect to specific financial institutions or the broader financial services industry may lead to market-wide liquidity shortages that could
materially  harm  our  business  and  financial  condition.  In  this  regard,  we  continue  to  maintain  our  cash  at  SVB  and  other  banks,  often  in
balances that exceed the current FDIC insurance limits, and the failure of any bank in which we deposit our funds could reduce the amount of
cash  we  have  available  for  our  operations  or  delay  our  ability  to  access  such  funds.  Any  such  failure  may  increase  the  possibility  of  a
sustained  deterioration  of  financial  market  liquidity,  or  illiquidity  at  clearing,  cash  management  and/or  custodial  financial  institutions.  In  the
event we have a commercial relationship with a bank that has failed or is otherwise distressed, we may experience delays or other issues in
meeting  our  financial  obligations.  If  other  banks  and  financial  institutions  fail  or  become  insolvent  in  the  future  in  response  to  financial
conditions affecting the banking system and financial markets, our ability to access our cash, cash equivalents and investments, including
transferring funds, making payments or receiving funds may be threatened and our ability to raise additional capital could be substantially
impaired,  any  of  which  could  materially  and  adversely  affect  our  business  and  financial  condition.  In  any  event,  if  the  financial  market
disruptions and economic slowdown deepen or persist, we may not be able to access additional capital on favorable terms, or at all, which
could negatively affect our financial condition and our ability to pursue our business strategy.

If  adequate  funds  are  not  available  from  public  or  private  equity  or  debt  offerings  on  acceptable  terms,  in  order  to  continue  the

development of our product candidates we may need to:

44

Table of Contents

•

•

seek strategic alliances for R&D programs when we otherwise would not, at an earlier stage than we would otherwise desire or on
terms less favorable than might otherwise be available; or

enter into BD Arrangements that could require us to relinquish, or license, on potentially unfavorable terms, our rights to intellectual
property, product candidates or products that we otherwise would develop or seek to commercialize ourselves.

In this regard, we will need to raise significant additional capital in order to conduct any potential registrational trial of aldafermin in
PSC. In addition, clinical development of NGM707 beyond completing the Phase 1 Part 1b cohort evaluating NGM707 in combination with
pembrolizumab, including initiating additional cohorts, will require us to obtain the additional capital necessary to conduct such development.
There is no guarantee that we will be able to raise sufficient additional capital in order to progress these key priorities in the event the Offer
and the Merger are not consummated, in which case, our business, operating results and prospects will be materially and adversely affected,
or we may be required to cease operations altogether.

Moreover, due to the need to conserve capital and prioritize focused execution, we are seeking BD Arrangements with third-party
partners with sufficient resources and relevant domain expertise in order to further the clinical development, if any, of NGM438, NGM831,
NGM621  and  NGM313.  Further  development  of  these  programs  is  dependent  on  our  ability  to  secure  potential  future  BD  Arrangements.
However, we may not be able to enter into such BD Arrangements on acceptable terms, if at all. We face significant competition in seeking
appropriate  partners.  Whether  we  would  reach  a  definitive  agreement  for  a  BD  Arrangement  will  depend,  among  other  things,  upon  the
potential  partner’s  evaluation  of  the  subject  product  candidate  and  its  market  opportunity,  our  assessment  of  the  partner’s  resources  and
expertise and the terms and conditions of the potential BD Arrangement. In the absence of such BD Arrangements for these programs, we
are  unlikely  to  be  able  to  advance  their  development  unless  our  portfolio  prioritization  changes  and  we  are  able  to  secure  the  additional
capital necessary to fund such development. For more information, see the risk factor titled “While the Offer and the Merger are pending, we
are  subject  to  business  uncertainties  and  contractual  restrictions  that  limit  our  ability  to  pursue  financing  or  BD  Arrangements  and  could
disrupt  our  business,  and  the  Offer  and  the  Merger  may  impair  our  ability  to  attract  and  retain  qualified  employees  or  retain  and  maintain
relationships with our suppliers and other business partners."

We  are  also  restricted  under  our  existing  Amended  Collaboration  Agreement  with  Merck,  and  may  be  restricted  under  future  BD
Arrangements, from entering into additional agreements on certain terms with potential partners. For example, under the current terms of the
Amended Collaboration Agreement, we may not directly or indirectly research, develop, manufacture or commercialize, except pursuant to
the  Amended  Collaboration  Agreement,  any  medicine  or  product  candidate  that  modulates  a  target  then  subject  to  the  collaboration  with
specified  activity.  In  addition,  under  the  Amended  Collaboration  Agreement,  we  are  prohibited  from,  directly  or  indirectly,  researching,
developing  or  commercializing  any  product  for  the  treatment  of  heart  failure  with  preserved  ejection  fraction  during  the  research  program
term  for  the  CVM-related  programs.  We  also  may  be  required  to  pay  a  low  single-digit  royalty  on  sales  of  certain  product  candidates  that
received funding from Merck and, if we decide, during a specified time period, to engage in partnering, licensing or asset sale negotiations
regarding certain of such product candidates, we are obligated to notify Merck, provide Merck with certain information and engage in good
faith, non-exclusive negotiations with respect to such product candidates. Such obligations may hamper our ability to successfully enter into
BD Arrangements for such programs with parties other than Merck.

We  may  not  be  able  to  raise  adequate  additional  capital  or  negotiate  potential  future  BD  Arrangements  on  a  timely  basis,  on
acceptable  terms  or  at  all.  If  we  are  unable  to  do  so,  we  may  need  to  significantly  delay,  scale  back  or  discontinue  development  of  or
abandon  some  or  all  of  our  product  candidates,  or  scale  back  or  discontinue  our  discovery  research  efforts,  any  of  which  could  have  a
material adverse effect on our business, operating results and prospects, or we may be required to cease operations altogether.

Raising additional capital may cause dilution to our existing stockholders, lead to restrictions on our operations or require us to
relinquish rights to our product candidates or intellectual property.

If we raise additional funds by issuing equity securities, our stockholders may experience dilution. Debt financing, if available, may
involve  restrictive  covenants.  Any  debt  financing  or  additional  equity  that  we  raise  may  contain  terms  that  are  not  favorable  to  us  or  our
stockholders.  Our  ability  to  raise  capital  may  be  adversely  impacted  by  the  trading  prices  of  our  common  stock  given  our  stock  price
performance over the past year. Furthermore, any securities that we may issue may have rights senior to those of our common stock and
could contain covenants or protective rights that would lead to restrictions on our operations and potentially impair our competitiveness, such
as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other
operating restrictions that could adversely impact our ability to conduct our business.

Risks Related to Our Dependence on Third Parties

We expect to depend in the future on BD Arrangements with third-party partners for the development and commercialization of our
product candidates and for revenue. If we are unable to secure those BD Arrangements on beneficial terms, if at all, or if any such
future  arrangements  are  not  successful,  we  may  not  be  able  to  capitalize  on  the  market  potential  of  our  product  candidates  or
continue their development.

Pursuing BD arrangements has been and is expected to continue to be a key component of our strategy, and we are seeking BD
Arrangements with third-party partners to progress, in whole or in part, the development of one or more of our product candidates. While we
will consider BD Arrangements to advance development of our programs, the further development of certain programs, including NGM438,
NGM831,  NGM621  and  NGM313,  is  dependent  on  our  ability  to  secure  potential  future  BD  Arrangements  for  these  programs.  Due  to  the
need  to  conserve  capital  and  prioritize  focused  execution  and  unless  our  portfolio  prioritization  changes,  if  we  are  unable  to  secure  BD
Arrangements for these programs on beneficial terms, if at all, we are unlikely to be able to advance their development unless our portfolio
prioritization changes and we are able to secure the additional capital necessary to fund such development. We may discontinue or abandon
any  or  all  of  our  programs  altogether,  in  which  case  we  will  not  realize  any  return  on  our  investments  in  these  programs.  Even  if  we  are
successful  in  entering  into  any  BD  Arrangements  with  third-party  partners  for  our  programs,  we  will  likely  have  limited  control  over  the
amount and timing of resources that our partners dedicate to the development or commercialization of the applicable product candidates. Our
ability to generate revenue from any such arrangement will depend on the specific financial terms we reach with any partner, as well as each
of our partners’ abilities to successfully perform the functions assigned to them in such arrangement towards developing, seeking regulatory
approval for and commercializing our product candidates.

BD Arrangements involving our product candidates pose risks to us, including the following:

•

•

•

•

•

•

Partners have significant discretion in determining the efforts and resources that they will apply to these arrangements. For example,
under  the  terms  of  the  collaboration  with  Merck,  if  Merck  exercises  its  option  to  acquire  an  exclusive  license  for  any  CVM-related
preclinical candidate that remains within the scope of the collaboration, our ability to influence the resources Merck devotes to such
candidate  are  substantially  reduced  until  such  time,  if  any,  that  we  exercise  our  right  to  participate  in  a  cost  and  profit  share
arrangement. Even after any exercise of the right to participate in a cost and profit share arrangement, our ability to influence Merck
would be limited.

Partners  might  opt  not  to  pursue  development  and  commercialization  of  our  product  candidates  or  not  to  continue  or  renew
development  or  commercialization  programs  based  on  clinical  trial  results,  changes  in  the  partner’s  strategic  focus  or  available
funding or external factors, such as an acquisition that diverts resources or creates competing priorities.

Partners may delay clinical trials, provide insufficient funding for a clinical trial program, request the suspension or termination of a
clinical trial or abandon a product candidate, repeat or conduct new clinical trials or require a new formulation of a product candidate
for clinical testing.

Partners  could  independently  develop,  or  develop  with  third  parties,  products  that  compete  directly  or  indirectly  with  our  product
candidates if the partners believe that competitive products are more likely to be successfully developed or can be commercialized
under terms that are more economically attractive than ours.

A partner with marketing and distribution rights might not commit sufficient resources to the marketing and distribution of our product
candidates.

Partners might not properly maintain or defend our intellectual property rights or may use our proprietary information in such a way
as to invite litigation that could jeopardize or invalidate our proprietary information or expose us to potential litigation.

• Disputes  may  arise  between  the  partners  and  us  that  result  in  the  delay  or  termination  of  the  research,  development  or
commercialization  of  our  product  candidates  or  that  result  in  costly  litigation  or  arbitration  that  diverts  management  attention  and
resources.

• We  may  lose  certain  valuable  rights  under  circumstances  identified  in  our  BD  Arrangements,  including  if  we  undergo  a  change  in

control.

•

•

BD Arrangements might be terminated and, if terminated, may result in a need for additional capital to pursue further development or
commercialization of the applicable product candidates.

BD Arrangements might not lead to development or commercialization of product candidates in the most efficient manner, or at all. If
a present or future partner of ours were to be involved in a business

46

Table of Contents

combination,  the  continued  pursuit  of  and  emphasis  on  our  product  development  or  commercialization  program  under  such
arrangement could be delayed, diminished or terminated.

With certain exceptions, we may not generally pursue potential future BD Arrangements for our programs during the pendency of the
Offer and the Merger. For more information, see the risk factor titled “While the Offer and the Merger are pending, we are subject to business
uncertainties and contractual restrictions that limit our ability to pursue financing or BD Arrangements and could disrupt our business, and the
Offer and the Merger may impair our ability to attract and retain qualified employees or retain and maintain relationships with our suppliers
and other business partners.”

We may not be able to obtain and maintain the relationships with third parties that are necessary to develop, commercialize and
manufacture some or all of our product candidates.

In  addition  to  our  dependence  on  any  potential  future  partners,  we  expect  to  depend  on  other  third  parties,  including  contract
research  organizations,  or  CROs,  clinical  data  management  organizations,  clinical 
investigators,  contract  manufacturing
organizations/contract  development  and  manufacturing  organizations,  or  CMOs,  and  other  third-party  partners  and  service  providers  to
support our discovery efforts, to formulate product candidates, to conduct our clinical trials and certain aspects of our research and preclinical
studies, to manufacture clinical and commercial-scale quantities of our drug substances and drug products and to market, sell and distribute
any  products  we  successfully  develop  and  for  which  we  obtain  regulatory  approval.  Any  problems  we  experience  with  any  of  these  third
parties  could  delay  our  research  efforts  or  the  development,  manufacturing  or  commercialization  of  our  product  candidates  or  any  future
products, which could harm our results of operations. For more information, see the risk factors titled “We rely completely on CMOs for the
manufacture of our product candidates, and we are subject to many manufacturing risks, any of which could substantially increase our costs
and  limit  supply  of  our  product  candidates  and  any  future  products"  and “We have no experience in sales, marketing and distribution and
may have to enter into agreements with third parties to perform these functions, which could prevent us from successfully commercializing
our product candidates.”

We  cannot  guarantee  that  we  or,  as  applicable,  any  of  our  partners  will  be  able  to  successfully  negotiate  agreements  for,  and
maintain relationships with, third-party partners and service providers on favorable terms, if at all. If we or any of our partners are unable to
obtain and maintain these agreements, we may not be able to clinically develop, formulate, manufacture, obtain regulatory approvals for or
commercialize  our  product  candidates,  which  will,  in  turn,  adversely  affect  our  business.  If  we  or  any  of  our  partners  need  to  enter  into
alternative  arrangements,  it  would  delay  our  product  development  and,  if  applicable,  commercialization  activities  and  such  alternative
arrangements may not be available on terms acceptable to us.

We  expect  to  continue  to  expend  substantial  management  time  and  effort  to  enter  into  relationships  with  third  parties  and,  if  we
successfully enter into such relationships, to manage these relationships. In addition, our reliance on these third parties for R&D activities
reduces our control over these activities but does not relieve us of our responsibilities. For example, we remain responsible for ensuring that
each  of  our  clinical  trials  is  conducted  in  accordance  with  the  general  investigational  plan  and  protocols  for  the  trial.  However,  we  cannot
control  the  amount  or  timing  of  resources  these  third  parties  will  devote  to  our  R&D  programs,  product  candidates  or  potential  product
candidates, and we cannot guarantee that these parties will fulfill their obligations to us under these arrangements in a timely fashion, if at all.
If these third parties do not successfully carry out their contractual duties, meet expected deadlines or conduct our clinical trials or other R&D
activities in accordance with regulatory requirements, we will not be able to obtain, or may be delayed in obtaining, marketing approvals for
our product candidates and will not be able to, or may be delayed in our efforts to, successfully commercialize any approved products. In
addition, we base our expense accruals related to clinical trials on our estimates of the services received and efforts expended pursuant to
contracts with multiple research institutions and CROs that conduct and manage clinical trials on our behalf and, if their estimates are not
accurate, it could negatively affect the accuracy of our financial statements.

Any agreements we have or may enter into with third-party partners and service providers may give rise to disputes regarding the
rights  and  obligations  of  the  parties.  Disagreements  could  develop  over  contract  interpretation,  rights  to  ownership  or  use  of  intellectual
property, the scope and direction of R&D, the approach for regulatory approvals or commercialization strategy. We are conducting research
programs  in  a  range  of  therapeutic  areas,  and  our  pursuit  of  these  opportunities  could  result  in  conflicts  with  the  other  parties  to  these
agreements that may be developing or selling pharmaceuticals or conducting other activities in these same therapeutic areas. Any disputes
or commercial conflicts could lead to the termination of our agreements, delay progress of our product development programs, compromise
our  ability  to  renew  agreements  or  obtain  future  agreements,  lead  to  the  loss  of  intellectual  property  rights,  result  in  increased  financial
obligations for us or result in costly and time-consuming arbitration or litigation.

47

Table of Contents

In addition, we are less knowledgeable about the reputation and quality of third-party contractors in countries outside of the United
States  where  we  conduct  discovery  research  or  preclinical  and  clinical  development  and  manufacturing  of  our  product  candidates  and,
therefore, we may not choose the best parties for these relationships.

We rely completely on CMOs for the manufacture of our product candidates, and we are subject to many manufacturing risks, any
of which could substantially increase our costs and limit supply of our product candidates and any future products.

We  have  limited  process  development  capabilities  and  require  the  services  of  third-party  CMOs  to  provide  additional  process
development and manufacturing capabilities. We do not have, and we do not currently plan to acquire or develop, the facilities or capabilities
to manufacture bulk drug substance or filled drug product for use in clinical trials or commercialization. As a result, we rely completely on
CMOs, which entails risks to which we would not be subject if we manufactured product candidates or products ourselves, including risks
related  to  reliance  on  third  parties  for  availability  of  drug  product  to  use  in  our  clinical  trials  and  for  regulatory  compliance  and  quality
assurance  with  respect  to  such  drug  product,  the  possibility  of  breach  of  the  manufacturing  agreement  by  third  parties  because  of  factors
beyond  our  control  (including  a  failure  to  manufacture  our  product  candidates  or  any  products  we  may  eventually  commercialize  in
accordance  with  our  specifications)  and  the  possibility  of  termination  or  nonrenewal  of  agreements  by  third  parties,  based  on  their  own
business priorities, at a time that is costly or damaging to us.

Our product candidates are biologics, and the manufacture of biologic products is complex, highly regulated and requires significant
expertise  and  capital  investment,  including  the  development  of  advanced  manufacturing  techniques  and  process  controls.  As  a  result,  the
manufacture of our product candidates is subject to many risks, including the following, some of which we have experienced:

•

•

•

•

product  loss  or  other  negative  consequences  due  to  contamination,  equipment  failure,  improper  installation  or  operation  of
equipment, vendor or operator error, shortages of qualified personnel or improper delivery or storage conditions;

difficulties  with  production  costs  and  yields,  quality  control,  product  stability  and  quality  assurance  testing,  including  challenges
related  to  bioanalytical  method  development  and  the  qualification  and  implementation  of  those  methods  for  release  testing,  which
can delay availability of clinical trial materials;
unexpected quality control results during stability program execution that may lead to shorter than anticipated shelf-life or drug expiry,
resulting in the need to manufacture additional batches or present other risks to our clinical supply chain;

the negative consequences of failure to comply with strictly enforced federal, state and foreign regulations;

• minor deviations from normal manufacturing processes, which have in the past and may in the future result in reduced production

yields, product defects and other supply disruptions;

•

•

•

•

the presence of microbial, viral or other contaminants discovered in our product candidates or in the manufacturing facilities in which
they are made, which can necessitate closure of facilities for an extended time period to investigate and eliminate the contamination;

the negative consequences of our CMOs’ failure to qualify upon an audit by regulatory authorities, by us or by our collaborators;

our CMOs’ changing strategies and business priorities, including as a result of changes in ownership, which can affect the availability
of facilities where we intend to manufacture our product candidates; and

our  CMOs  or  their  manufacturing  facilities  being  adversely  affected  by  labor,  raw  material  and  component  shortages,  turnover  of
qualified staff or financial difficulties of their owners or operators, including as a result of the effects of financial market disruptions
and economic slowdowns, or by disease outbreaks, epidemics, pandemics, natural disasters, power failures, local political unrest or
other factors.

For  example,  a  CMO  that  produces  aldafermin  drug  product  was  inspected  by  the  FDA  in  2022  and  2023  and  received  multiple
critical  Form  483  observations  on  its  aseptic  fill/finish  GMP  operations.  If  the  CMO  fails  to  address  the  FDA's  concerns  to  the  agency's
satisfaction through the CMO's corrective actions, the CMO may receive additional warnings and, if we were to seek regulatory approval of
aldafermin,  any  product  that  is  manufactured  on  an  affected  line  may  not  be  qualified  by  the  FDA,  which  could  delay  regulatory  timelines
significantly. Furthermore, the CMO recently announced a pending acquisition by an independent pharmaceutical entity. The potential impact
on our longer-term ability to manufacture with this CMO is unknown at this time and may

48

Table of Contents

result in the need to perform a tech transfer to an alternate location, potentially increasing cost, delaying timelines and increasing program
risks.

We, our CMOs, any future collaborators and their contract manufacturers could be subject to periodic unannounced inspections by
the FDA, competent authorities of EU Member States or other comparable foreign regulatory authorities, to monitor and ensure compliance
with cGMP. Despite our efforts to audit and verify regulatory compliance, one or more of our third-party manufacturing vendors may be found
on regulatory inspection by the FDA, competent authorities of EU Member States or other comparable foreign regulatory authorities to be
noncompliant with cGMP regulations. Our failure, or the failure of our third-party manufacturers, to comply with applicable regulations could
result in sanctions being imposed on us, including shutdown of the third-party vendor or invalidation of drug product lots or processes, fines,
injunctions,  civil  penalties,  delays,  suspension,  variation  or  withdrawal  of  approvals,  license  revocation,  seizures  or  recalls  of  product
candidates  or  drugs,  operating  restrictions  and  criminal  prosecutions,  any  of  which  could  significantly  and  adversely  affect  supplies  of  our
products, if approved, and significantly harm our business, financial condition, results of operations and prospects.

We cannot ensure that issues relating to the manufacture or testing of our product candidates, such as those described above, will
not occur or continue to occur in the future and if we or our CMOs experience any such issues there could be a shortage of drug substance
or drug product for use in our clinical trials, which could delay clinical and regulatory timelines significantly and have an adverse effect on our
business.

In  addition,  to  date  our  product  candidates  have  been  manufactured  by  CMOs  solely  for  preclinical  studies  and  relatively  small
clinical trials. We intend to continue to use CMOs for these purposes, and for the supply of larger quantities that may be required to conduct
accelerated  or  expanded  early  clinical  trials  or  larger,  later  clinical  trials  and  for  commercialization  if  we  advance  any  of  our  product
candidates through regulatory approval and to commercialization. These manufacturers may not have sufficient manufacturing capacity and
may not be able to scale up the production of drug substance or drug product in the quantities we need and at the level of quality required in
a timely or effective manner, or at all. In particular, there is increased competition in the biotechnology industry for CMO manufacturing slots
and other capabilities generally, which has had, and may continue to have, a negative impact on the availability of manufacturing capacity
and therefore our ability to supply clinical trial materials for planned, ongoing or expanded clinical trials. Industry drug shortages, especially in
prefilled  syringe  products  such  as  GLP-1  agonists,  may  have  a  knock-on  effect  for  clinical  pipeline  products  we  produce  that  use  similar
syringe components or utilize syringe fill/finish manufacturing lines.

The transfer of our small-scale manufacturing processes to CMOs for scale up and validation and any later scale up and validation of
the manufacturing process in the CMOs’ facilities to manufacture larger quantities, involve difficult and complex processes. We may not be
successful in transferring our production system to a CMO, either because it is unable to implement the process successfully in its facilities or
for other reasons. Later scale-up activities are also difficult and costly and entail risks such as process reproducibility, stability, consistency
and other technical challenges. If we are unable to adequately validate or scale up the manufacturing processes for our product candidates,
we would need to undertake a transfer to another third party and repeat the manufacturing validation process, which can be expensive and
time-consuming and could delay the initiation or completion of our clinical trials.

Similarly,  we  or  our  CMOs  may  make  changes  to  our  product  candidates’  manufacturing  processes  at  various  points  in  product
development  for  many  reasons,  including  scaling  up,  facility  fit,  raw  material  or  component  availability,  decreasing  costs  or  timing  of
production, improving processing robustness and reliability, decreasing processing times or others. Such changes require further validation
and may have unintended consequences, which could include causing our product candidates to perform differently when administered in
clinical  trials  and  affecting  clinical  trial  results.  In  some  circumstances,  we  may  be  required  to  perform  comparability  or  other  studies  to
demonstrate that the product used in earlier clinical trials or at earlier stages of a trial are comparable to the product we intend to use in later
trials  or  later  stages  of  an  ongoing  trial.  These  efforts  are  expensive  and  there  is  no  assurance  that  they  will  be  successful,  which  could
impact our ability to continue or initiate clinical trials in a timely manner, or at all.

Any future adverse developments affecting manufacturing operations or the scale up or validation of manufacturing processes for our
product candidates may result in shipment delays, lot failures, clinical trial delays or discontinuations, or, if we are commercializing products,
inventory shortages, product withdrawals or recalls or other interruptions in supply. We may also have to record inventory write-offs and incur
other charges and expenses for drug substance or drug product that fails to meet specifications or cannot be used before its expiration date.
In  addition,  for  out  of  specification  materials,  we  may  need  to  undertake  costly  remediation  efforts  or  manufacture  new  batches  at
considerable cost and time delays or, in the longer run, seek more expensive manufacturing alternatives.

49

Table of Contents

We  also  have  a  single  source  of  supply  for  most  of  our  product  candidates,  including  the  drug  substances  used  in  manufacturing
them. Single sourcing minimizes our leverage with our CMOs, who may take advantage of our reliance on them to increase the pricing of
their  manufacturing  services  or  require  us  to  change  our  intended  manufacturing  plans  based  on  their  strategies  and  priorities.  Single
sourcing also imposes a risk of interruption or delays in supply in the event of manufacturing, quality or compliance difficulties and/or other
difficulties in timely supplying us with materials. We have in the past, and we may in the future, experience supply-related delays that would
adversely affect our ability to commence first-in-human testing of product candidates on our anticipated timing. Moreover, we do not currently
have arrangements in place for redundant supply for drug substance or drug product. If one of our suppliers fails or refuses to supply us for
any reason or we otherwise choose to engage a new supplier for one or more of our product candidates, including a second source supplier
to  mitigate  the  risks  of  single-source  supply,  it  would  take  a  significant  amount  of  time  and  cost  to  implement  and  execute  the  necessary
technology transfer to, and qualification of, a new supplier. The FDA or comparable foreign health authority must approve manufacturers of
drug  substance  and  drug  product.  If  there  are  any  delays  in  qualifying  new  suppliers  or  facilities  or  a  new  supplier  is  unable  to  meet  the
requirements of the FDA or comparable foreign health authority for approval, there could be a shortage of drug substance or drug product for
use in clinical trials with respect to the affected product candidates which would adversely affect our ability to continue and complete clinical
trials on our anticipated timing or at all.

Our  product  candidates  use  certain  raw  materials  for  their  production,  such  as  reagents  that  support  cell  growth,  purification
materials  and  testing  and  manufacturing  supplies.  Some  of  these  materials  only  have  a  single  supplier  and  are  purchased  as  necessary
without  a  long-term  supply  agreement  in  place.  If  our  CMOs  are  required  to  obtain  an  alternative  source  of  certain  raw  materials  and
components, additional testing, validation activities and regulatory approvals may be required, which may negatively impact manufacturing
and other development timelines. For example, in 2021, one of our CMOs experienced shortages of the specific cell culture media used to
manufacture  one  of  our  products  due  to  global  supply  chain  challenges  and,  while  we  have  been  successful  in  obtaining  a  replacement
product, these types of substitutions may require additional and unplanned testing, qualification or validation activities. Any significant delay
in the acquisition or decrease in the availability of these materials, components or other items, or failure to successfully qualify or validate
alternative materials or components, could considerably delay the manufacture of our product candidates, which could adversely impact the
timing or completion of any ongoing and planned trials or the timing of regulatory approvals, if any, of our product candidates.

In addition, our CMOs’ facilities and operations have been adversely affected by labor, raw material and component shortages, high
turnover  of  staff  and  difficulties  in  hiring  trained  and  qualified  replacement  staff  and  the  operations  of  our  CMOs  may  be  requisitioned,
diverted or allocated by U.S. or foreign government orders such as under emergency, disaster and civil defense declarations in connection
with the COVID-19 pandemic or otherwise.

Some of our product candidates are currently solely manufactured at a facility in Lithuania. Following Russia's invasion of Ukraine in
February  2022,  the  response  from  the  United  States  and  its  allies  has  included  both  significant  sanctions  and  NATO's  deployment  of
additional  military  forces  to  Eastern  Europe,  including  to  Lithuania.  The  ongoing  conflict  between  Russia  and  Ukraine  and  the  retaliatory
measures taken or that may be taken by the United States, NATO and others, including significant sanctions against Russia, create global
security concerns and regional instability, including due to the possibility of expanded regional or global conflict, and are likely to continue to
have short-term and likely longer-term negative impacts on regional and global economies, any or all of which could disrupt our supply chain
and  adversely  affect  our  ability  to  conduct  ongoing  and  future  clinical  trials  of  our  product  candidates  and  our  ability  to  raise  capital  on
favorable terms.

Any further delays or interruptions in the supply of clinical trial material could delay the completion or initiation of our clinical trials,
increase the costs associated with maintaining clinical trial programs and, depending upon the period of delay, require us to commence new
clinical trials at additional expense, terminate ongoing clinical trials or abandon planned clinical trials or expansions or accelerations of clinical
trials completely.

We have no experience in sales, marketing and distribution and may have to enter into agreements with third parties to perform
these functions, which could prevent us from successfully commercializing our product candidates.

We currently have no sales, marketing or distribution capabilities. To commercialize our product candidates, we must either develop
our own sales, marketing and distribution capabilities or make arrangements with third parties to perform these services for us. If we decide
to  market  any  of  our  products  on  our  own,  we  will  have  to  commit  significant  resources  to  developing  a  marketing  and  sales  force  and
supporting distribution capabilities. If we decide to enter into arrangements with third parties for performance of these services, we may find
that they are not

50

Table of Contents

available on terms acceptable to us, or at all. If we are not able to establish and maintain successful arrangements with third parties or build
our own sales and marketing infrastructure, we may not be able to commercialize our product candidates, which would adversely affect our
business, operating results and prospects.

Risks Related to Our Business and Industry

Our  product  candidates  must  undergo  rigorous  clinical  trials  before  seeking  regulatory  approvals,  and  clinical  trials  may  be
delayed, suspended or terminated at any time for many reasons, any of which could delay or prevent regulatory approval and, if
approval is granted, commercialization of our product candidates.

All  of  our  product  candidates  are  subject  to  rigorous  and  extensive  clinical  trials  before  we  can  seek  regulatory  approval  from  the
FDA and comparable foreign health authorities such as the European Commission. Clinical trials may be delayed, suspended or terminated
at any time for reasons including but not limited to:

•

•

•

•

•

•

•

•

•

•

•

ongoing discussions with the FDA or comparable foreign health authorities regarding the scope or design of our clinical trials, such
as our discussions with the FDA regarding the design of the PSC registrational trial and whether we will be successful producing a
toxicology  package  to  support  the  potential  initiation  of  a  Phase  2  proof-of-concept  trial  of  NGM120  in  patients  with  hyperemesis
gravidarum, or HG;

delays  in  obtaining,  or  the  inability  to  obtain,  required  approvals  from  institutional  review  boards  and  ethics  committees  or  other
governing entities at clinical trial sites selected for participation in our clinical trials;

delays in patient enrollment and other key trial activities, including as a result of the significant competition for recruiting patients with
cancer in clinical trials and difficulty recruiting pregnant women to participate in clinical trials of NGM120 in HG;

delays in reaching agreement on acceptable terms with prospective CROs and the failure of CROs, testing laboratories and other
third parties to satisfy their contractual duties to us or meet expected deadlines;

deviations from the trial protocol by clinical trial sites and investigators, or failures to conduct the trial in accordance with regulatory
requirements;

lower than anticipated retention rates of participants in clinical trials, including patients dropping out due to side effects or disease
progression;

failure of enrolled patients to complete treatment or to return for post-treatment follow-up;

for clinical trials in selected patient populations, delays in identification and auditing of central or other laboratories and the transfer
and validation of assays or tests to be used to identify selected patients and test any patient samples;

implementation of new, or changes to, guidance or interpretations from the FDA or comparable foreign health authorities with respect
to approval pathways for product candidates we are pursuing, such as with respect to the proposed utilization of a primary endpoint
composed of surrogate biomarkers with the goal of obtaining accelerated approval for aldafermin for the treatment of PSC;

the  need  to  repeat  clinical  trials  as  a  result  of  inconclusive  or  negative  results,  poorly  executed  testing  or  changes  in  required
endpoints;

insufficient supply or deficient quality of drug substance, drug product or other clinical trial material necessary to conduct our clinical
trials, as well as delays in the testing, validation, manufacturing and delivery to clinical trial sites of such material;

• withdrawal of clinical trial sites or investigators from our clinical trials for any reason, including as a result of changing standards of

care or the ineligibility of a site to participate in our clinical trials;

•

•

•

•

•

•

unfavorable  FDA  or  comparable  foreign  health  authority  inspection  or  review  of  a  clinical  trial  site  or  records  of  any  clinical  or
preclinical investigation;

drug-related adverse effects or tolerability issues experienced by participants in our clinical trials;

changes in government regulations or administrative actions;

lack  of  adequate  funding  to  continue  the  clinical  trials,  particularly  given  our  need  to  obtain  additional  capital  in  order  to  continue
clinical  development  of  NGM707  beyond  completing  the  Phase  1  Part  1b  cohort,  including  initiating  additional  cohorts,  and  to
conduct a registrational trial of aldafermin in patients with PSC;

our ability to hire and retain key R&D personnel; or

the placement of a clinical hold on a trial by the FDA or comparable foreign health authorities.

We cannot guarantee that we will be able to successfully accomplish required regulatory and/or manufacturing activities or all of the
other activities necessary to initiate and complete clinical trials in a timely fashion, if at all. As a result, our preclinical studies and clinical trials
may be extended, delayed or terminated, and we may be unable to obtain regulatory approvals or successfully commercialize our products.
For example, we may need to conduct additional toxicology studies not currently planned in order to produce a toxicology package to support
the potential initiation of a Phase 2 proof-of-concept trial of NGM120 in patients with HG. We also have only limited experience in conducting
late-stage clinical trials required to obtain regulatory approval. In any event, we do not know whether any of our clinical trials will begin as
planned, will need to be restructured or will be completed on schedule, or at all.

Our  product  development  costs  will  increase  if  we  experience  delays  in  clinical  testing.  Significant  clinical  trial  delays  could  also
shorten any periods during which we may have the exclusive right to commercialize our product candidates or allow our competitors to bring
products  to  market  before  we  do,  which  would  impair  our  ability  to  successfully  commercialize  our  product  candidates  and  may  harm  our
business, results of operations and prospects. Our or our partners’ inability to timely complete clinical development could result in additional
costs to us or impair our ability to generate product revenue or development, regulatory, commercialization and sales milestone payments
and royalties on product sales.

If clinical trials of our product candidates fail to produce positive results or to demonstrate safety and efficacy to the satisfaction of
the FDA or comparable health authorities or sufficient to demonstrate differentiation from other approved therapies or therapies in
development,  we  may  incur  additional  costs  or  experience  delays  in  completing,  or  ultimately  be  unable  to  complete,  the
development and commercialization of our product candidates.

Our product candidates are in early stages of development, with our most advanced product candidate within our key priorities for
clinical development only in Phase 2 development. Before obtaining marketing approval from health authorities for the sale of our product
candidates,  we  or  our  partners  must  conduct  extensive  preclinical  studies  and  clinical  trials  to  demonstrate  the  safety  and  efficacy  of  the
product candidates in humans. Preclinical studies and clinical trials are expensive, take several years to complete and may not yield results
that  support  further  clinical  development  or  product  approvals.  The  design  of  a  clinical  trial  can  determine  whether  its  results  will  support
approval of a product, and flaws in the design of a clinical trial may not become apparent until the clinical trial is well advanced. Because we
have limited experience designing clinical trials, we may be unable to design and execute a clinical trial to support regulatory approval.

In addition, there is a high failure rate for drugs and biologic products proceeding through clinical trials and failure can occur at any
stage  of  testing.  For  example,  despite  the  results  of  preclinical  and  Phase  1  studies  of  NGM621,  our  Phase  2  CATALINA  clinical  trial
evaluating  NGM621  in  patients  with  geographic  atrophy,  or  GA,  secondary  to  advanced  macular  degeneration,  or  AMD,  did  not  meet  its
primary  endpoint.  Similarly,  our  Phase  2b  ALPINE  2/3  trial  evaluating  aldafermin  in  patients  with  nonalcoholic  steatohepatitis  liver  fibrosis
stage 2 or 3, or F2/F3 NASH, did not meet its primary endpoint and, as a result, we decided to suspend further development of aldafermin in
patients with F2/F3 NASH, allowing for the reallocation of resources to advancing our other programs.

Moreover, if we or a future partner seek accelerated approval for one of our product candidates based on a surrogate endpoint, the
FDA may not accept such endpoint, may require additional studies or analysis or may not approve our product candidate on an accelerated
basis, or at all. For example, we are designing a potential registrational trial of aldafermin in PSC and continuing discussions with the FDA,
including  on  the  proposed  utilization  of  a  primary  endpoint  composed  of  surrogate  biomarkers  with  the  goal  of  obtaining  accelerated
approval. There is no guarantee that the FDA will accept our proposed primary endpoint, in which case we may abandon the development of
aldafermin in PSC.

Further,  we  expect  that  certain  of  our  current  product  candidates  will,  and  future  product  candidates  may,  require  chronic
administration. The need for chronic administration increases the risk that participants in our clinical trials will fail to comply with our dosing
regimens. If participants fail to comply, we may not be able to generate clinical data in our trials acceptable to the FDA or comparable foreign
health authorities. The need for chronic administration also increases the risk that our clinical drug development programs may not uncover
all possible adverse events that patients who take our products may eventually experience. The number of patients exposed to treatment
with, and the average exposure time to, our product candidates in clinical development programs may be inadequate to detect rare adverse
events or chance findings that may only be detected once our products are administered to more patients and for longer periods of time.

We may also not be successful in generating clinical data sufficient to differentiate our product candidates from other products in the

same therapeutic area. If our competitors' products are, or are perceived to be, more

52

Table of Contents

effective, more convenient, less costly or safer than our products, or we are unable to demonstrate differentiation in any of those factors, we
may  not  be  able  to  achieve  a  competitive  position  in  the  market.  For  more  information,  refer  to  the  risk  factor  titled  “We  face  substantial
competition, which may result in others discovering, developing or commercializing products before or more successfully than us."

In  addition,  data  obtained  from  preclinical  and  clinical  activities  are  subject  to  varying  interpretations,  which  may  delay,  limit  or
prevent regulatory approval. In any event, it is impossible to predict when or if any of our product candidates will prove safe and effective in
humans or will receive regulatory approval. If we are unable to successfully discover, develop or enable our partners to develop drugs that
regulatory authorities deem effective and safe in humans, we will not have a viable business.

Success in preclinical studies or earlier-stage clinical trials may not be indicative of results in future clinical trials.

To date, the data supporting our drug discovery and development programs are derived from laboratory and preclinical studies and
earlier-stage clinical trials. Owing in part to the complexity of biological pathways, when used to treat human patients, our product candidates
might  not  demonstrate  the  biochemical  and  pharmacological  properties  we  anticipate  based  on  laboratory  studies  or  earlier-stage  clinical
trials, and they may interact with human biological systems or other drugs in unforeseen, ineffective or harmful ways. Success in preclinical
studies and earlier-stage clinical trials does not ensure that later clinical trials will generate the same results or otherwise provide adequate
data  to  demonstrate  the  effectiveness  and  safety  of  our  product  candidates.  In  this  regard,  the  data  supporting  our  drug  discovery  and
development programs are derived from laboratory and preclinical studies, and future clinical trials in humans may show that one or more of
our product candidates are not safe and effective, in which event we may need to abandon development of such product candidates. In fact,
many companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in late-stage clinical trials even after
achieving promising results in preclinical studies and earlier-stage clinical trials. Preliminary data and interim results from clinical trials may
not  be  predictive  of  final  results.  For  example,  despite  the  results  of  preclinical  and  Phase  1  studies  of  NGM621,  our  Phase  2  CATALINA
clinical trial evaluating NGM621 in patients with GA secondary to AMD did not meet its primary endpoint. Similarly, in spite of the results we
had obtained in our Phase 1 trials of aldafermin and in our first Phase 2 trial, in May 2021, we announced that our Phase 2b ALPINE 2/3 trial
evaluating aldafermin in patients with F2/F3 NASH did not meet its primary endpoint. For more information, refer to the risk factor titled “If
clinical trials of our product candidates fail to produce positive results or to demonstrate safety and efficacy to the satisfaction of the FDA or
comparable health authorities or sufficient to demonstrate differentiation from other approved therapies or therapies in development, we may
incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of our
product candidates." There  can  be  no  assurance  that  any  clinical  testing  of  our  product  candidates  will  be  successful  or  will  otherwise  be
supportive of continued development and/or regulatory approvals of such product candidates.

In  addition,  some  of  our  earlier-stage  clinical  trials  involve  small  patient  populations,  sometimes  at  single  sites,  and  the  results  of
these  clinical  trials  may  be  subject  to  substantial  variability  and  may  not  be  indicative  of  either  future  interim  results  or  final  results.  As  a
general matter, there is also a substantial risk that Phase 3 trials with larger numbers of patients and/or longer durations of therapy will fail to
replicate efficacy and safety results observed in earlier clinical trials.

Our product candidates may cause undesirable side effects or adverse events or have other properties or safety risks, which could
delay or prevent continued clinical development or their regulatory approval or limit the commercial profile of any approved label.

Adverse  events,  undesirable  side  effects  or  similar  safety  issues  caused  by  our  product  candidates  could  cause  us  or  health
authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by
the FDA or other comparable foreign health authorities. Additional clinical trials may be required to further evaluate the safety profile of our
product  candidates.  Patients  in  certain  of  our  ongoing  or  planned  clinical  trials,  particularly  patients  with  cancer,  often  enter  our  trials  with
significant  comorbidities  or  advanced  life-threatening  illness  and/or  are  treated  in  the  trial  with  our  product  candidate  in  combination  with
other medications, including, in cancer patients, chemotherapy or other approved cancer treatments. As a result, patients in our clinical trials
can be expected to experience some adverse events, including death, or side effects that are not or may not be related to treatment with our
product candidates. Nonetheless, the occurrence of adverse events or side effects, whether or not related to our product candidates, could
impact the success of our clinical trials.

53

Table of Contents

Patients  experienced,  and  we  reported,  serious  adverse  events,  or  SAEs,  in  the  treatment  arms  of  completed  trials  of  NGM313,
NGM621  and  aldafermin.  We  expect  that  patients  in  our  clinical  trials,  including  those  that  are  sham-  or  placebo-controlled  with  some
patients not receiving study drug, will continue to experience adverse events and SAEs and we will continue to monitor those SAEs for any
signals of concern regarding the safety and tolerability of our product candidates. For example, cancer patients enrolled in our solid tumor
oncology clinical trials suffer from advanced life-threatening illness and have experienced, and we expect will continue to experience, SAEs
and other adverse events, which may or may not be drug-related. If patients in any of our clinical trials experience a high or unacceptable
severity  and  prevalence  of  side  effects,  including  particularly  SAEs,  it  could  affect  patient  recruitment  or  the  ability  of  enrolled  patients  to
complete their treatment in a clinical trial, it may result in a regulatory authority putting a clinical hold on the clinical trial or it may result in
failure to obtain regulatory approval for our product candidates or product liability claims.

Our product candidates are protein or antibody therapeutics. Protein and antibody therapeutics can sometimes induce host immune
responses that can cause the production of anti-drug antibodies, or ADAs. In some cases, ADAs have no effect. In other cases, ADAs may
neutralize the effectiveness of the product candidate, can require that higher doses be used to obtain a therapeutic effect or can cross react
with  substances  naturally  occurring  in  a  subject’s  body,  which  can  cause  unintended  effects,  including  potential  impacts  on  efficacy  and
adverse events. If we determine that ADAs are causing safety or efficacy concerns when using any of our product candidates, we may need
to delay or halt clinical trials of our product candidates and the affected product candidates may never obtain regulatory approval. We cannot
provide assurance that the detection of ADAs will not be higher than we have observed historically or that observed rates will not later be
found to limit drug exposure or cause adverse safety events, or that the detection of ADAs will not otherwise result in the non-approvability of
any of our product candidates.

Future results of our trials could reveal a high and unacceptable severity and prevalence of side effects, SAEs, ADAs, safety issues
or other negative or otherwise unexpected characteristics. The occurrence of those issues could affect patient recruitment or the ability of
enrolled  patients  to  complete  their  treatment  in  a  clinical  trial,  result  in  failure  to  obtain  regulatory  approval  for  our  product  candidates  or
product  liability  claims  or  impact  market  acceptance  of  our  products.  Any  of  these  occurrences  could  materially  and  adversely  affect  our
business, financial condition and prospects.

We may not successfully identify new product candidates to expand our development pipeline.

The success of our business over the longer term depends upon our ability to identify and validate new potential protein and antibody
therapeutics. Research programs to identify new product candidates require substantial technical, financial and human resources, and our
research  methodology  may  not  successfully  identify  medically  relevant  protein  or  antibody  therapeutics  to  be  developed  as  product
candidates. In addition, our drug discovery efforts often identify and select novel, untested proteins in the particular disease indication we are
pursuing, which we may fail to validate after further research work. Moreover, our research efforts may initially show promise in discovering
potential new protein and antibody therapeutics yet fail to yield product candidates for clinical development for multiple reasons. For example,
potential product candidates may, on further study, be shown to have inadequate efficacy, harmful side effects, suboptimal drug profiles or
other characteristics suggesting that they are unlikely to be commercially viable products. Our inability to successfully identify additional new
product candidates to advance into clinical trials could have a material adverse effect on our business, operating results and prospects.

We  may  fail  to  select  or  capitalize  on  the  most  scientifically,  clinically  and  commercially  promising  or  profitable  product
candidates.

We have limited technical, managerial and financial resources to determine which of our product candidates should proceed to initial
clinical trials, later-stage clinical development and potential commercialization. We may make incorrect determinations in allocating resources
among  these  product  candidates.  Our  decisions  to  allocate  our  R&D,  management  and  financial  resources  toward  particular  product
candidates  or  therapeutic  areas  may  not  lead  to  the  development  of  viable  commercial  products  and  may  divert  resources  from  better
opportunities. For example, our pipeline programs in development include product candidates in solid tumor oncology, and we had previously
been focusing the majority of our execution efforts and resources on these programs. Several of our early trials in solid tumor oncology did
not show sufficiently promising results to support further investment at this time, and, as a result, we have redirected our focus to targeted
oncology indications for NGM707 and for a new indication, HG, for NGM120. We have also redirected our clinical development efforts for
aldafermin away from NASH to PSC. However, our new areas of focus may be unsuccessful and may never lead to the development of

54

Table of Contents

viable commercial products. Similarly, our decisions to delay or terminate certain drug development programs to concentrate our resources
elsewhere may be incorrect and could cause us to miss valuable opportunities.

We must attract and retain highly skilled employees in order to succeed. If we are not able to retain our current senior management
team, or to continue to attract and retain qualified scientific, technical and business personnel, our business will suffer.

To succeed, we must recruit, retain, manage and motivate qualified clinical, scientific, technical and management personnel and we
face significant competition for experienced personnel. If we do not succeed in attracting and retaining qualified personnel, particularly at the
management level, it could adversely affect our ability to execute our business plan and harm our operating results. In 2023, we announced a
restructuring of our workforce, reducing our existing headcount by approximately 33%, that our founder, Dr. Jin-Long Chen, resigned from the
Board and his position as Chief Scientific Officer, that Siobhan Nolan Mangini was stepping down as Chief Financial Officer and President,
and  that  Jean-Frédéric  Viret,  Ph.D.  was  appointed  as  our  new  Chief  Financial  Officer.  These  significant  changes  have  caused  additional
attrition of employees and may cause further attrition of employees, including senior management, and negatively affect employee morale.
Additionally,  as  we  are  operating  our  business  with  fewer  employees,  including  fewer  members  of  senior  management,  the  loss  of  a
significant number of our remaining employees or of any of our current executive officers could result in a significant loss in the knowledge
and experience that we, as an organization, possess and could cause significant delays, or outright failure, in the development and further
commercialization of our product candidates.

There is intense competition for qualified personnel, including management, in the technical fields in which we operate, and we may
not be able to attract and retain qualified personnel necessary for the successful research, development and future commercialization, if any,
of our product candidates. We recruit for talent in the biotechnology and pharmaceutical industry in the San Francisco Bay Area, which is one
of  the  most  competitive  and  highest  cost  labor  markets  in  the  United  States  and  periodically  experiences  higher  turnover  rates  than  other
industries.

Many  of  the  other  pharmaceutical  companies  that  we  compete  against  for  qualified  personnel  have  greater  financial  and  other
resources, different risk profiles and a longer history in the industry than we do. They also may provide more diverse opportunities and better
chances  for  career  advancement.  Some  of  these  characteristics  may  be  more  appealing  to  high-quality  candidates  than  what  we  have  to
offer. See also the risk factor titled “While the Offer and the Merger are pending, we are subject to business uncertainties and contractual
restrictions that limit our ability to pursue financing or BD Arrangements and could disrupt our business, and the Offer and the Merger may
impair  our  ability  to  attract  and  retain  qualified  employees  or  retain  and  maintain  relationships  with  our  suppliers  and  other  business
partners."  If  we  experience  higher  than  expected  employee  attrition  rates,  it  could  have  a  negative  impact  on  our  productivity.  If  we  are
unable to attract and retain high-quality personnel, the rate and success with which we can discover and develop product candidates and our
business will be limited.

We face substantial competition, which may result in others discovering, developing or commercializing products before or more
successfully than us.

The biopharmaceutical industry is intensely competitive and subject to rapid and significant technological change. Our competitors
include  multinational  pharmaceutical  companies,  specialized  biotechnology  companies  and  universities  and  other  research  institutions.  A
number of pharmaceutical and biotechnology companies are pursuing the development or marketing of pharmaceuticals that seek to treat
the same diseases that we are pursuing with our most advanced product candidates. Some of these pharmaceuticals in development are
active, or seek to be active, against the same targets that our product candidates are engineered to effect. It is probable that the number of
companies seeking to develop products and therapies that compete with our product candidates will increase. Many of our competitors have
substantially greater financial, technical, human and other resources than we do and may be better equipped to develop, manufacture and
market  technologically  superior  products.  In  addition,  many  of  these  competitors  have  significantly  greater  experience  than  we  have  in
undertaking  preclinical  studies  and  human  clinical  trials  of  new  pharmaceutical  products  and  in  obtaining  regulatory  approvals  of  human
therapeutic  products.  Accordingly,  our  competitors  may  succeed  in  obtaining  FDA  approval  and  approval  or  marketing  authorization  from
comparable  health  authorities  such  as  the  European  Commission  for  superior  products  or  for  other  products  that  would  compete  with  our
product  candidates.  Many  of  our  competitors  have  established  distribution  channels  and  commercial  infrastructure  to  support  the
commercialization  of  their  products,  whereas  we  have  no  such  channel  or  capabilities.  In  addition,  many  competitors  have  greater  name
recognition  and  more  extensive  collaboration  or  partnering  relationships.  Smaller  and  earlier-stage  companies  may  also  prove  to  be
significant competitors, particularly through collaboration or partnering arrangements with large, established companies.

55

Table of Contents

Our  competitors  may  obtain  regulatory  approval  of  their  products  more  rapidly  than  us  or  may  obtain  patent  protection  or  other
intellectual property rights that limit our ability to develop or commercialize our product candidates. Our competitors may also develop drugs
that  are  more  effective,  more  convenient,  more  widely  used  and  less  costly  or  have  a  better  safety  profile  than  our  products  and  these
competitors  may  also  be  more  successful  than  us  in  manufacturing  and  marketing  their  products.  If  we  are  unable  to  compete  effectively
against these companies, then we may not be able to commercialize our product candidates or achieve a competitive position in the market.
These companies also compete with us in recruiting and retaining qualified scientific, management and commercial personnel, establishing
clinical  trial  sites  and  patient  registration  for  clinical  trials,  as  well  as  in  acquiring  technologies  complementary  to,  or  necessary  for,  our
programs.

Although we believe there are no FDA- or European Commission-approved therapies that specifically target the signaling pathways
that  our  current  product  candidates  are  designed  to  modulate  or  inhibit,  there  are  numerous  currently  approved  or  otherwise  widely  used
therapies for treating the same diseases or indications for which our product candidates may be useful. Some of these therapies act through
mechanisms  similar  to  our  product  candidates  or  are  well-established  therapies  or  products  widely  accepted  by  physicians,  patients  and
third-party payors. Some of these drugs are branded and subject to patent protection, and others are available on a generic basis. Insurers
and  other  third-party  payors  may  also  encourage  the  use  of  generic  products  or  specific  branded  products.  We  expect  that  if  our  product
candidates are approved, they will be priced at a significant premium over competitive generic products, including branded generic products.
This  may  make  it  difficult  for  us  to  differentiate  our  products  from  currently  approved  therapies,  which  may  adversely  impact  our  business
strategy.  In  addition,  many  companies  are  developing  new  therapeutics,  and  we  cannot  predict  what  the  standard  of  care  will  be  as  our
product candidates progress through clinical development. For more information regarding the competition that our most advanced product
candidates face, or may face, see the discussion of specific competition for each product candidate in “Business-Our Pipeline” in this Annual
Report.

Our product candidates may not achieve adequate market acceptance among physicians, patients, healthcare payors and others in
the medical community necessary for commercial success.

Demonstrating  the  safety  and  efficacy  of  our  product  candidates  and  obtaining  regulatory  approvals  will  not  guarantee  future
revenue.  Even  if  our  product  candidates  receive  regulatory  approval,  they  may  not  gain  adequate  market  acceptance  among  physicians,
patients,  healthcare  payors  and  others  in  the  medical  community.  The  degree  of  market  acceptance  of  any  of  our  approved  product
candidates will depend on a number of factors, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

the efficacy and safety profile of the product candidate as demonstrated in clinical trials;

the timing of market introduction of the product candidate, as well as competitive products;

the clinical indications for which the product candidate is approved;

acceptance of the product candidate as a safe and effective treatment by physicians and patients;

the actual and perceived advantages of the product candidate over alternative treatments, including any similar generic treatments;

the viewpoints of influential physicians with respect to the product candidate;

the inclusion or exclusion of the product candidate from treatment guidelines established by various physician groups;

the cost of treatment relative to alternative treatments;

our pricing and the availability of coverage and adequate reimbursement by third parties and government authorities as described in
the risk factor titled “Even if we obtain approval to market our products, these products may become subject to unfavorable pricing
regulations, reimbursement practices from third-party payors or healthcare reform initiatives in the United States and abroad, which
could harm our business”;

the relative convenience and ease of administration;

the frequency and severity of adverse events;

the effectiveness of sales and marketing efforts; and

any unfavorable publicity relating to the product candidate.

For example, aldafermin is administered via a once-daily subcutaneous injection, which may negatively impact market acceptance of
an approved aldafermin product, if any. In addition, refer to the risk factor titled “Our product candidates may cause undesirable side effects
or adverse events or have other properties or safety risks, which could delay or prevent continued clinical development or their regulatory
approval or limit the commercial profile of any approved label." If any product candidate is approved but does not achieve an adequate level
of

56

Table of Contents

acceptance by such parties, we may not generate or derive sufficient revenue from that product candidate and may not become or remain
profitable.

Even  if  we  obtain  approval  to  market  our  products,  these  products  may  become  subject  to  unfavorable  pricing  regulations,
reimbursement  practices  from  third-party  payors  or  healthcare  reform  initiatives  in  the  United  States  and  abroad,  which  could
harm our business.

The  regulations  that  govern  pricing  and  reimbursement  for  new  drug  products  vary  widely  from  country  to  country.  In  the  United
States,  there  has  been  increasing  executive,  legislative  and  enforcement  interest  with  respect  to  drug  pricing  practices.  There  have  been
U.S.  congressional  inquiries,  presidential  executive  orders  and  proposed  and  enacted  legislation  designed  to,  among  other  things,  bring
more  transparency  to  drug  pricing,  reduce  the  cost  of  prescription  drugs  under  Medicare,  review  the  relationship  between  pricing  and
manufacturer  patient  programs  and  reform  government  program  reimbursement  methodologies  for  drugs.  We  expect  that  the  healthcare
reform measures that have been adopted and may be adopted in the future in the United States may result in more rigorous coverage criteria
and additional downward pressure on the price that we receive for any approved product and could seriously harm our future revenues. Any
reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors.
The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain
profitability or commercialize our products.

In many regions outside of the United States, including the European Union, or EU, Japan and Canada, the pricing of prescription
drugs is already controlled by the government and some countries require approval of the sale price of a drug before it can be marketed. In
many countries, the pricing review period begins after regulatory approval for the product is granted. As a result, we might obtain marketing
approval for a product in a particular country, but then be subject to price regulations that delay or limit our commercial launch of the product,
possibly  for  lengthy  time  periods,  which  could  negatively  impact  the  revenue  we  generate  from  the  sale  of  the  product  in  that  particular
country.

In  approving  the  sale  price  for  a  marketed  drug,  many  countries  outside  of  the  United  States  implement  health  technology
assessment,  or  HTA,  procedures  that  use  formal  economic  metrics  such  as  cost  effectiveness  to  determine  prices,  coverage  and
reimbursement of new therapies. These assessments are increasingly implemented in established and emerging markets and could require
us to compile additional data comparing the cost-effectiveness of our products to other available therapies. Efforts to generate additional data
for  the  HTA  process  could  involve  additional  expenses  which  may  substantially  increase  the  cost  of  commercializing  and  marketing  our
products outside the United States. Regulatory agencies may also determine that the pricing for our products should be based on prices of
other commercially available drugs for the same disease, rather than allowing us to market our products at a premium as new drugs. Adverse
pricing limitations, either before or after initial approvals, may hinder our ability to recoup our investment in one or more product candidates,
even if our product candidates obtain marketing approval. If we are unable to maintain favorable pricing status in EU member states or other
countries that represent significant markets, our anticipated revenue from and growth prospects for our products from those regions could be
negatively affected.

In  many  countries  outside  the  United  States,  government-sponsored  healthcare  systems  are  the  primary  payors  for  drugs.  With
increasing  budgetary  constraints  and/or  difficulty  in  understanding  the  value  of  medicines,  governments  and  payors  in  many  countries  are
applying  a  variety  of  measures  to  exert  downward  price  pressure  and  we  expect  that  legislators,  policy  makers  and  healthcare  insurance
funds  in  the  EU  member  states  will  continue  to  propose  and  implement  cost  cutting  measures.  These  measures  include  mandatory  price
controls,  price  referencing,  therapeutic-reference  pricing,  increases  in  mandates,  incentives  for  generic  substitution  and  biosimilar  usage,
government-mandated price cuts, limitations on coverage of target population and introduction of volume caps.

Our commercial success also depends on coverage and adequate reimbursement of our product candidates by third-party payors,
which may be difficult or time-consuming to obtain, may be limited in scope and may not be obtained in all jurisdictions in which we may seek
to market our products. Governments and private insurers closely examine medical products to determine whether they should be covered
by reimbursement and, if so, the level of reimbursement that will apply. Government authorities and other third-party payors have attempted
to control costs by limiting coverage and the amount of reimbursement for particular drugs. Increasingly, third-party payors are requiring that
drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for drug products. We
cannot  be  sure  that  coverage  and  reimbursement  will  be  available  for  any  product  that  we  or  our  partners  commercialize  and,  if
reimbursement is available, what the level of reimbursement will be. Coverage and reimbursement may impact the demand for, or the price
of, any product

57

Table of Contents

candidate  for  which  we  or  our  partners  obtain  regulatory  approval.  If  coverage  and  reimbursement  are  not  available  or  reimbursement  is
available  only  to  limited  levels,  we  and  our  partners  may  not  be  able  to  successfully  commercialize  any  product  candidate  for  which
marketing approval is obtained.

We  cannot  predict  the  likelihood,  nature  or  extent  of  healthcare  reform  initiatives  that  may  arise  from  future  legislation  or
administrative  action.  If  we  or  any  third  parties  we  may  engage  are  slow  or  unable  to  adapt  to  changes  in  existing  requirements  or  the
adoption of new requirements or policies, or if we or such third parties are not able to maintain regulatory compliance, our product candidates
may lose any regulatory approval that may have been obtained and we may not achieve or sustain profitability.

Our  international  operations  may  expose  us  to  business,  regulatory,  political,  operational,  financial,  pricing  and  reimbursement
risks associated with doing business outside of the United States.

Our business is subject to risks associated with conducting business internationally. Some of our suppliers and clinical trial sites are
located  outside  of  the  United  States.  Furthermore,  if  we  or  any  future  partner  succeeds  in  developing  any  of  our  product  candidates,  we
intend to market them in the EU and other jurisdictions in addition to the United States. If approved, we or any future partner may hire sales
representatives and conduct physician and patient association outreach activities outside of the United States. Doing business internationally
involves a number of challenges and risks, including but not limited to:

• multiple, conflicting and changing laws and regulations, such as privacy and data protection regulations, tax laws, export and import

restrictions, employment laws, regulatory requirements and other governmental approvals, permits and licenses;

•

•

•

•

•

•

•

•

•

•

•

failure by us to obtain and maintain regulatory approvals for the use of our products in various countries;

rejection or qualification of foreign clinical trial data by the competent authorities of other countries;

delays or interruptions in the supply of clinical trial material resulting from any events affecting raw material or component supply or
manufacturing capabilities abroad;

additional potentially relevant third-party patent rights;

complexities and difficulties in obtaining, maintaining, protecting and enforcing our intellectual property;

difficulties in staffing and managing foreign operations;

complexities associated with managing multiple payor reimbursement regimes, government payors or patient self-pay systems;

limits on our ability to penetrate international markets;

financial risks, such as longer payment cycles, difficulty collecting accounts receivable, the impact of inflation and local and regional
financial crises on demand and payment for our products and exposure to foreign currency exchange rate fluctuations;

natural  disasters,  political,  geopolitical  and  economic  instability,  including  wars  such  as  the  conflict  between  Russia  and  Ukraine,
terrorism  and  political  unrest,  disease  outbreaks,  epidemics  and  pandemics,  boycotts,  curtailment  of  trade  and  other  business
restrictions; and

regulatory and compliance risks that relate to anti-corruption compliance and record-keeping that may fall within the purview of the
U.S.  Foreign  Corrupt  Practices  Act,  its  accounting  provisions  or  its  anti-bribery  provisions  or  provisions  of  anti-corruption  or  anti-
bribery laws in other countries.

Any  of  these  factors  could  harm  our  ongoing  international  clinical  operations  and  supply  chain,  as  well  as  any  future  international

expansion and operations and, consequently, our business, financial condition, prospects and results of operations.

Product liability lawsuits against us could cause us to incur substantial liabilities and to limit commercialization of any products
that we may develop.

We face an inherent risk of product liability exposure related to the testing of our product candidates in human clinical trials and will
face an even greater risk if we or our partner commercializes any resulting products. This risk is heightened in regard to the potential Phase 2
proof-of-concept study of NGM120 for the treatment of HG given the highly vulnerable potential patient population involved. Product liability
claims may be brought against us by subjects enrolled in our clinical trials, patients, healthcare providers or others using, administering or
selling our products. If we cannot successfully defend ourselves against claims that our product candidates or products that we may develop
caused injuries, we could incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in:

58

Table of Contents

•

•

•

decreased demand for any product candidates or products that we may develop;

termination of clinical trial sites or entire trial programs;

injury to our reputation and significant negative media attention;

• withdrawal of clinical trial participants;

•

•

•

•

•

significant costs to defend the related litigation;

substantial monetary awards to trial subjects or patients;

loss of revenue;

diversion of management and scientific resources from our business operations; and

the inability to commercialize any products that we may develop.

Our  clinical  trial  liability  insurance  coverage  may  not  adequately  cover  all  liabilities  that  we  may  incur.  We  may  not  be  able  to
maintain  insurance  coverage  at  a  reasonable  cost  or  in  an  amount  adequate  to  satisfy  any  liability  that  may  arise.  Our  inability  to  obtain
product liability insurance at an acceptable cost or to otherwise protect against potential product liability claims could prevent or delay the
commercialization  of  any  products  or  product  candidates  that  we  develop.  We  intend  to  expand  our  insurance  coverage  for  products  to
include the sale of commercial products if we obtain marketing approval for our product candidates in development, but we may be unable to
obtain commercially reasonable product liability insurance for any products approved for marketing. Large judgments have been awarded in
class  action  lawsuits  based  on  drugs  that  had  unanticipated  side  effects.  If  we  are  sued  for  any  injury  caused  by  our  products,  product
candidates  or  processes,  our  liability  could  exceed  our  product  liability  insurance  coverage  and  our  total  assets.  Claims  against  us,
regardless of their merit or potential outcome, may also generate negative publicity or hurt our ability to obtain physician endorsement of our
products or expand our business.

Our relationships with healthcare providers, customers and third-party payors will be subject to applicable anti-kickback, fraud and
abuse, transparency and other healthcare laws and regulations, which, if violated, could expose us to criminal sanctions, civil
penalties, contractual damages, reputational harm, administrative burdens and diminished profits and future earnings.

Healthcare providers, including physicians, and third-party payors will play a primary role in the recommendation and prescription of
any  product  candidates  for  which  we  or  our  partner  obtains  marketing  approval.  Our  arrangements  with  healthcare  providers,  third-party
payors and customers may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations that may constrain
the business or financial arrangements and relationships through which we research, market, sell and distribute our products for which we or
our partner obtain marketing approval. Restrictions under applicable federal and state healthcare laws and regulations, include the following:

•

•

•

the federal Anti-Kickback Statute prohibits persons from, among other things, knowingly and willfully soliciting, offering, receiving or
providing remuneration, directly or indirectly, in cash or in kind, to induce or reward, or in return for, the referral of an individual for the
furnishing or arranging for the furnishing, or the purchase, lease or order, or arranging for or recommending purchase, lease or order,
of any good or service for which payment may be made under a federal healthcare program, such as Medicare and Medicaid;

the federal False Claims Act, or FCA, imposes criminal and civil penalties, including through civil whistleblower or qui tam actions,
against individuals or entities for knowingly presenting, or causing to be presented, to the federal government, claims for payment
that  are  false  or  fraudulent  or  making  a  false  statement  to  avoid,  decrease  or  conceal  an  obligation  to  pay  money  to  the  federal
government;

the  federal  Health  Insurance  Portability  and  Accountability  Act,  or  HIPAA,  imposes  criminal  liability  for  knowingly  and  willfully
executing  a  scheme  to  defraud  any  healthcare  benefit  program,  knowingly  and  willfully  embezzling  or  stealing  from  a  healthcare
benefit  program,  willfully  obstructing  a  criminal  investigation  of  a  healthcare  offense  or  knowingly  and  willfully  making  false
statements relating to healthcare matters;

• HIPAA,  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical  Health  Act  of  2009  and  its  implementing
regulations,  or  HITECH,  also  imposes  obligations  on  certain  covered  entity  healthcare  providers,  health  plans  and  healthcare
clearinghouses, and their business associates that perform certain services involving the use or disclosure of individually identifiable
health information as well as their covered subcontractors, including mandatory contractual terms, with respect to safeguarding the
privacy, security, processing and transmission of individually identifiable health information;

59

Table of Contents

•

•

the  federal  Physician  Payments  Sunshine  Act,  as  amended,  and  its  implementing  regulations,  requires  manufacturers  of  drugs,
devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance
Program (with certain exceptions) to report annually to the HHS information related to “payments or other transfers of value” made to
physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors), other health care professionals (such as
physician  assistants  and  nurse  practitioners)  and  teaching  hospitals,  as  well  as  information  regarding  ownership  and  investment
interests held by physicians and their immediate family members; and

analogous state and foreign laws and regulations, such as state and foreign anti-kickback and false claims laws, which may apply to
sales  or  marketing  arrangements  and  claims  involving  healthcare  items  or  services  reimbursed  by  non-governmental  third-party
payors, including private insurers; state and foreign laws that require pharmaceutical companies to comply with the pharmaceutical
industry’s  voluntary  compliance  guidelines  and  the  relevant  compliance  guidance  promulgated  by  the  federal  government  or
otherwise  restrict  payments  that  may  be  made  to  healthcare  providers;  state  and  local  laws  requiring  the  registration  of
pharmaceutical  sales  representatives;  state  and  foreign  laws  that  require  drug  manufacturers  to  report  information  related  to
payments and other transfers of value to physicians and other healthcare providers, marketing expenditures or pricing; and state and
foreign laws that govern the privacy and security and other processing of health information in certain circumstances, many of which
differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations will
involve substantial costs. It is possible that governmental authorities will conclude that our business practices may not comply with current or
future statutes, regulations or case law interpreting applicable fraud and abuse or other healthcare laws and regulations. If our operations are
found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil,
criminal  and  administrative  penalties,  damages,  fines,  additional  regulatory  oversight,  litigation,  imprisonment,  exclusion  from  government
funded healthcare programs, such as Medicare and Medicaid, and the curtailment or restructuring of our operations. If any of the physicians
or  other  healthcare  providers  or  entities  with  whom  we  expect  to  do  business  is  found  not  to  be  in  compliance  with  applicable  laws,  that
person  or  entity  may  be  subject  to  criminal,  civil  or  administrative  sanctions,  including  exclusions  from  government  funded  healthcare
programs.

Outside the United States, interactions between pharmaceutical companies and health care professionals are also governed by strict
laws, such as national anti-bribery laws of EU member states, national sunshine rules, regulations, industry self-regulation codes of conduct
and physicians’ codes of professional conduct. Failure to comply with these requirements could result in reputational risk, public reprimands,
administrative penalties, fines or imprisonment.

Our  business  could  be  materially  and  adversely  affected  in  the  future  by  the  effects  of  disease  outbreaks,  epidemics  and
pandemics.

Disease  outbreaks,  epidemics  and  pandemics  in  regions  where  we  have  clinical  trial  sites  or  other  business  operations  could
adversely  affect  our  business,  including  by  causing  significant  disruptions  in  our  operations  and/or  in  the  operations  of  third-party
manufacturers and CROs upon whom we rely. Disease outbreaks, epidemics and pandemics have negative impacts on our ability to initiate
new clinical trial sites, to enroll new patients and to maintain existing patients who are participating in our clinical trials, which may include
increased clinical trial costs, longer timelines and delay in our ability to obtain regulatory approvals of our product candidates, if at all. For
example, our ability to attract additional clinical trial sites and principal investigators to conduct our clinical trials and to conduct the necessary
clinical  trial  site  initiation  procedures  was  impacted  by  COVID-19  quarantines,  shelter-in-place  and  similar  restrictions  imposed  by  federal,
state and local governments. In addition, during the COVID-19 pandemic, we experienced, from time to time, a slower pace of clinical site
initiation  and  clinical  trial  enrollment  and  a  higher  subject  dropout  rate  than  originally  anticipated  in  certain  of  our  clinical  trials,  which  we
believe  may  have  been  due  to  factors  such  as  the  vulnerability  of  our  studied  patient  populations,  site  staff  shortages,  clinical  trial  site
suspensions, reallocation of medical resources and the challenges of working remotely due to shelter-in-place and similar government orders
and guidelines, among other factors.

General  supply  chain  issues  may  be  exacerbated  during  disease  outbreaks,  epidemics  and  pandemics  and  may  also  impact  the
ability of our clinical trial sites to obtain basic medical supplies used in our trials in a timely fashion, if at all. In addition, our CMOs’ facilities
and operations were adversely affected by labor, raw material and component shortages, high turnover of staff and difficulties in hiring trained
and qualified replacement staff during the COVID-19 pandemic. These difficulties resulted in some delays in early development timelines and
we  could  experience  more  significant  disruptions  to  our  supply  chain  and  operations  as  a  result  of  disease  outbreaks,  epidemics  or
pandemics in the future. If our CMOs are required to obtain an alternative source of certain raw

60

Table of Contents

materials  and  components,  for  example,  additional  testing,  validation  activities  and  regulatory  approvals  may  be  required  which  can  also
have  a  negative  impact  on  timelines.  Any  associated  delays  in  the  manufacturing  and  supply  of  drug  substance  and  drug  product  for  our
clinical  trials  could  adversely  affect  our  ability  to  conduct  ongoing  and  future  clinical  trials  of  our  product  candidates  on  our  anticipated
development  timelines.  Likewise,  the  operations  of  our  third-party  manufacturers  may  be  requisitioned,  diverted  or  allocated  by  U.S.  or
foreign  government  orders  such  as  under  emergency,  disaster  and  civil  defense  declarations  in  connection  with  future  disease  outbreaks,
epidemics  or  pandemics.  For  example,  early  in  the  COVID-19  pandemic,  our  aldafermin  drug  product  CMO  advised  us  that  it  could  be
required under orders of the U.S. government to allocate manufacturing capacity to the manufacture or distribution of COVID-19 vaccines. If
any  of  our  CMOs  or  raw  materials  or  components  suppliers  become  subject  to  acts  or  orders  of  U.S.  or  foreign  government  entities  to
allocate or prioritize manufacturing capacity, raw materials or components to the manufacture or distribution of vaccines or medical supplies
needed to test or treat patients in a disease outbreak, epidemic or pandemic, this could delay our clinical trials, perhaps substantially, which
could materially and adversely affect our business.

To  the  extent  the  effects  of  any  future  disease  outbreak,  epidemic  or  pandemic  adversely  affect  our  business  and  results  of
operations, it also may have the effect of heightening many of the other risks and uncertainties described elsewhere in this "Risk Factors"
section.

Risks Related to Regulatory Approvals

The regulatory approval processes of the FDA and comparable foreign health authorities are lengthy and inherently unpredictable.
Our inability to obtain regulatory approval for our product candidates would substantially harm our business.

Currently,  none  of  our  product  candidates  has  received  regulatory  approval  and  we  do  not  expect  our  product  candidates  to  be
commercially  available  for  several  years,  if  at  all.  The  time  required  to  obtain  approval  from  the  FDA  and  comparable  foreign  health
authorities is unpredictable but typically takes many years following the commencement of preclinical studies and clinical trials and depends
upon numerous factors, including the substantial discretion of the health authorities. In addition, approval policies, regulations or the type and
amount of preclinical and clinical data necessary to gain approval may change during the course of a product candidate’s development and
may vary among jurisdictions. It is possible that none of our existing or future product candidates will ever obtain regulatory approval.

Our  product  candidates  could  fail  to  receive  regulatory  approval  from  the  FDA  or  a  comparable  foreign  health  authority  for  many

reasons, including:

•

•

•

•

•

•

•

•

•

disagreement with the design or implementation of our clinical trials;

failure to demonstrate that a product candidate is safe and effective for its proposed indication;

failure of results of clinical trials to meet the level of statistical significance required for approval;

failure to demonstrate that a product candidate’s clinical and other benefits outweigh its safety risks;

disagreement with our interpretation of data from preclinical studies or clinical trials;

the insufficiency of data collected from clinical trials to support the submission and filing of a biologics license application, or BLA, or
other submission or to obtain regulatory approval;

failure to obtain approval of the manufacturing processes or facilities of third-party manufacturers with whom we contract for clinical
and commercial supplies;

unfavorable quality review or audit/inspection findings; or

changes in the approval policies or regulations that render our preclinical and clinical data insufficient for approval.

The FDA or a comparable foreign health authority may require more information, including additional preclinical or clinical data, to
support approval, which may delay or prevent approval and commercialization, or we may decide to abandon the development program for
other reasons. If we obtain approval, regulatory authorities may approve any of our product candidates for fewer or more limited indications
than we request, may grant accelerated approval or conditional marketing authorization based on a surrogate endpoint and contingent on the
successful outcome of costly post-marketing confirmatory clinical trials or may approve a product candidate with a label that does not include
the labeling claims necessary or desirable for the successful commercialization of that product candidate. In this regard, we are designing a
potential registrational trial of aldafermin in PSC and continuing discussions with the FDA, including on the proposed utilization of a primary
endpoint composed of

61

Table of Contents

surrogate biomarkers with the goal of obtaining accelerated approval. There is no guarantee that the FDA will accept our proposed primary
endpoint, in which case, we may abandon the development of aldafermin in PSC.

If  we  or  a  future  partner  seek  accelerated  approval  for  one  of  our  product  candidates,  such  as  aldafermin  in  PSC,  based  on  a
surrogate  endpoint,  the  FDA  may  not  accept  such  endpoint,  may  require  additional  studies  or  analysis  or  may  not  approve  our  product
candidate on an accelerated basis, or at all. In addition, if full approval is granted for another product in the same indication for which we are
seeking  accelerated  approval  for  one  of  our  product  candidates,  the  accelerated  approval  pathway  may  no  longer  be  available  to  us  or  a
future partner for our product candidate.

Our  failure  to  obtain  health  authority  approval  in  foreign  jurisdictions  would  prevent  us  from  marketing  our  product  candidates
outside the United States.

If  we  or  our  partners  succeed  in  developing  any  products,  we  intend  to  market  them  in  the  EU  and  other  foreign  jurisdictions  in
addition to the United States. In order to market and sell our products in other jurisdictions, we must obtain separate marketing approvals and
comply  with  numerous  and  varying  regulatory  requirements.  The  approval  procedure  varies  among  countries  and  can  involve  additional
testing.  The  time  required  to  obtain  approval  may  differ  substantially  from  that  required  to  obtain  FDA  approval.  The  regulatory  approval
process outside the United States generally includes all of the risks associated with obtaining FDA approval. In addition, in many countries
outside the United States, we must secure product pricing and reimbursement approvals before health authorities will approve the product for
sale  in  that  country.  Obtaining  foreign  regulatory  approvals  and  compliance  with  foreign  regulatory  requirements  could  result  in  significant
delays,  difficulties  and  costs  for  us  and  could  delay  or  prevent  the  introduction  of  our  products  in  certain  countries.  Further,  clinical  trials
conducted  in  one  country  may  not  be  accepted  by  health  authorities  in  other  countries  and  regulatory  approval  in  one  country  does  not
ensure approval in any other country, while a failure or delay in obtaining regulatory approval in one country may have a negative effect on
the  regulatory  approval  process  in  others.  If  we  fail  to  obtain  approval  of  any  of  our  product  candidates  by  health  authorities  in  another
country,  we  will  be  unable  to  commercialize  our  product  in  that  country,  and  the  commercial  prospects  of  that  product  candidate  and  our
business prospects could decline.

Even if our product candidates receive regulatory approval, they may still face future development and regulatory difficulties.

Even  if  we  obtain  regulatory  approval  for  a  product  candidate,  it  would  be  subject  to  ongoing  requirements  by  the  FDA  and
comparable  foreign  health  authorities  governing  the  manufacture,  quality  control,  further  development,  labeling,  packaging,  storage,
distribution,  safety  surveillance,  import,  export,  advertising,  promotion,  recordkeeping  and  reporting  of  safety  and  other  post-market
information. The FDA and comparable foreign health authorities will continue to closely monitor the safety profile of any product even after
approval. If the FDA or comparable foreign health authorities become aware of new safety information after approval of any of our product
candidates, they may require labeling changes or establishment of a Risk Evaluation and Mitigation Strategy, or REMS, or similar strategy,
impose significant restrictions on a product’s indicated uses or marketing or impose ongoing requirements for potentially costly post-approval
studies or post-market surveillance. Failure to comply with any related obligations may result in the suspension, variation or withdrawal of an
obtained approval and in civil and/or criminal penalties. Receipt of approval for narrower indications than sought, restrictions on marketing
through  a  REMS  or  similar  strategy  imposed  in  an  EU  member  state  or  other  foreign  country,  or  significant  labeling  restrictions  or
requirements in an approved label such as a boxed warning, could have a negative impact on our ability to recoup our R&D costs and to
successfully  commercialize  that  product,  any  of  which  could  materially  and  adversely  affect  our  business,  financial  condition,  results  of
operations  and  growth  prospects.  In  any  event,  if  we  are  unable  to  comply  with  our  post-marketing  obligations  imposed  as  part  of  the
marketing approvals in the United States, the EU, or other countries, our approval may be varied, suspended or revoked, product supply may
be delayed and our sales of our products could be materially adversely affected.

In  addition,  manufacturers  of  drug  substance  and  drug  products  and  their  facilities  are  subject  to  continual  review  and  periodic
inspections  by  the  FDA  and  comparable  foreign  health  authorities  for  compliance  with  current  Good  Manufacturing  Practices,  or  cGMP,
regulations. If we or a regulatory authority discover previously unknown problems with a product, such as adverse events of unanticipated
severity or frequency, or problems with the facility where the product is manufactured, a regulatory authority may impose restrictions on that
product,  the  manufacturing  facility  or  us,  including  requiring  recall  or  withdrawal  of  the  product  from  the  market  or  suspension  of
manufacturing. If we or the manufacturing facilities for our product candidates fail to comply with applicable regulatory requirements, or if our
product candidates are found to cause undesirable or unacceptable side effects, a regulatory authority may:

62

Table of Contents

•

issue  safety  alerts,  Dear  Healthcare  Provider  letters,  press  releases  or  other  communications  containing  warnings  about  such
product;

• mandate modifications to promotional materials or require us to provide corrective information to healthcare practitioners;

•

•

•

•

•

•

•

•

require that we conduct and complete post-marketing studies;

require  us  to  enter  into  a  consent  decree,  which  can  include  imposition  of  various  fines,  reimbursements  for  inspection  costs,
required due dates for specific actions and penalties for noncompliance;

seek an injunction or impose civil or criminal penalties or monetary fines;

suspend marketing of, withdraw or vary regulatory approval of or initiate a recall of such product;

suspend any ongoing clinical trials;

refuse to approve pending applications or supplements to applications filed by us;

suspend or impose restrictions on operations, including costly new manufacturing requirements; or

seize or detain products or refuse to permit the import or export of products.

The occurrence of any event or penalty described above may inhibit our ability to commercialize our products and generate revenue.

Advertising and promotion of any product candidate that obtains approval in the United States will be heavily scrutinized by the FDA,
Department of Justice, HHS, Office of Inspector General, state attorneys general, members of Congress and the public. Violations, including
promotion  of  our  products  for  unapproved  (or  off-label)  uses,  are  subject  to  enforcement  letters,  inquiries  and  investigations  and  civil  and
criminal  sanctions  by  the  government.  Additionally,  comparable  foreign  health  authorities,  public  prosecutors,  industry  associations,
healthcare professionals and other members of the public will heavily scrutinize advertising and promotion of any product candidate outside
of the United States.

In  the  United  States,  engaging  in  the  impermissible  promotion  of  our  products  for  off-label  uses  can  subject  us  to  false  claims
litigation under federal and state statutes, which can lead to civil and criminal penalties and fines and agreements that materially restrict the
manner in which a company promotes or distributes drug products. These false claims statutes include the federal FCA, which allows any
individual to bring a lawsuit against a pharmaceutical company on behalf of the federal government alleging submission of false or fraudulent
claims,  or  causing  to  present  such  false  or  fraudulent  claims,  for  payment  by  a  federal  program  such  as  Medicare  or  Medicaid.  If  the
government  prevails  in  the  lawsuit,  the  individual  will  share  in  any  fines  or  settlement  funds.  Since  2004,  these  FCA  lawsuits  against
pharmaceutical companies have increased significantly in volume and breadth, leading to several substantial civil and criminal settlements
regarding certain sales practices promoting off-label drug uses involving fines in excess of $1 billion. This growth in litigation has increased
the  risk  that  a  pharmaceutical  company  will  have  to  defend  a  false  claim  action,  pay  settlement  fines  or  restitution,  agree  to  comply  with
burdensome  reporting  and  compliance  obligations  and  be  excluded  from  Medicare,  Medicaid  and  other  federal  and  state  healthcare
programs.  If  we  do  not  lawfully  promote  our  approved  products,  we  may  become  subject  to  such  litigation  and,  if  we  do  not  successfully
defend against such actions, those actions may have a material adverse effect on our business, financial condition and results of operations.

In  the  EU,  the  advertising  and  promotion  of  medicinal  products  are  subject  to  both  EU  and  EU  member  state  laws  governing
promotion  of  medicinal  products,  interactions  with  physicians  and  other  healthcare  professionals,  misleading  and  comparative  advertising
and unfair commercial practices. Although general requirements for advertising and promotion of medicinal products are established under
EU  directives,  the  details  are  governed  by  regulations  in  each  member  state  and  can  differ  from  one  country  to  another.  For  example,
applicable  laws  require  that  promotional  materials  and  advertising  in  relation  to  medicinal  products  comply  with  the  product’s  Summary  of
Product Characteristics, or SmPC, as approved by the competent authorities in connection with a marketing authorization. The SmPC is the
document  that  provides  information  to  physicians  concerning  the  safe  and  effective  use  of  the  product.  Promotional  activity  that  does  not
comply with the SmPC is considered off-label and is prohibited in the EU. Promotion materials and advertising may also require approval by
competent  authorities  in  certain  European  Economic  Area,  or  EEA,  countries.  Direct-to-consumer  advertising  of  prescription  medicinal
products is also prohibited in the EU.

Failure  to  comply  with  EU,  EU  member  state,  and  other  country  laws  that  apply  to  the  conduct  of  clinical  trials,  manufacturing
approval,  marketing  authorization  of  medicinal  products  and  marketing  of  such  products,  both  before  and  after  grant  of  a  marketing
authorization, or with other applicable regulatory requirements, may result in administrative, civil or criminal penalties. These penalties could
include delays or refusal to authorize the conduct of

63

Table of Contents

clinical trials, or to grant marketing authorization, product withdrawals and recalls, product seizures, suspension, withdrawal or variation of
the  marketing  authorization,  total  or  partial  suspension  of  production,  distribution,  manufacturing  or  clinical  trials,  operating  restrictions,
injunctions,  suspension  of  licenses,  fines  and  criminal  penalties.  In  addition,  legislation  adopted  at  the  EU  level  may  be  implemented
differently by individual EU member states. These regulations, and their differing implementations in EU member states, increase our legal
and financial compliance costs and may make some activities more time-consuming and expensive.

Even  if  we  are  able  to  obtain  regulatory  approvals  for  any  of  our  product  candidates,  if  they  exhibit  harmful  side  effects  after
approval, our regulatory approvals could be revoked or otherwise negatively impacted.

Even if we receive regulatory approval for any of our product candidates, we will have tested them in only a small number of patients
during  our  clinical  trials.  If  an  application  for  marketing  is  approved  for  any  of  our  product  candidates  and  more  patients  begin  to  use  our
product,  new  risks  and  side  effects  associated  with  our  products  may  be  discovered.  As  a  result,  health  authorities  may  revoke  their
approvals.  Additionally,  we  may  be  required  to  conduct  additional  clinical  trials,  make  changes  in  labeling  of  our  product,  reformulate  our
product or make changes and obtain new approvals for our and our suppliers’ manufacturing facilities for our product candidates. Equivalent
obligations could be imposed by the foreign health authorities. We might have to withdraw or recall our products from the marketplace. We
may also experience a significant drop in the potential sales of our product if and when regulatory approvals for such product are obtained,
experience  harm  to  our  reputation  in  the  marketplace  or  become  subject  to  lawsuits,  including  class  actions.  Any  of  these  results  could
decrease or prevent any sales of our approved product or substantially increase the costs and expenses of commercializing and marketing
our product.

Risks Related to Our Intellectual Property

Our success depends in significant part upon our ability to obtain and maintain intellectual property protection for our products
and technologies.

Our  success  depends  in  significant  part  on  our  ability  and  the  ability  of  our  current  or  future  licensors,  licensees,  partners  or
collaborators to establish and maintain adequate intellectual property covering the product candidates that we plan to develop. In addition to
taking other steps designed to protect our intellectual property, we have applied for, and intend to continue applying for, patents with claims
covering  our  technologies,  processes  and  product  candidates  when  and  where  we  deem  it  appropriate  to  do  so.  However,  the  patent
prosecution process is expensive and time-consuming, and we and our current or future licensors, licensees, partners or collaborators may
not be able to prepare, file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. It is also
possible  that  we  or  our  current  or  future  licensors,  licensees,  partners  or  collaborators  will  fail  to  identify  patentable  aspects  of  inventions
made in the course of development and commercialization activities before it is too late to obtain patent protection for them. Pending and
future patent applications filed by us or our current or future licensors, licensees, partners or collaborators may not result in patents being
issued that protect our technology or product candidates, or products resulting therefrom, in whole or in part, or that effectively prevent others
from commercializing competitive technologies and products.

We have filed numerous patent applications both in the United States and in certain foreign jurisdictions to obtain patent rights to our
inventions, with claims directed to compositions-of-matter, methods of use, formulations, combination therapy and other technologies relating
to our product candidates. There can be no assurance that any of these patent applications will issue as patents or, for those applications
that  do  mature  into  patents,  whether  the  claims  of  the  patents  will  exclude  others  from  making,  using  or  selling  our  product  or  product
candidates, or products or product candidates that are substantially similar to ours. In countries where we have not and do not seek patent
protection,  third  parties  may  be  able  to  manufacture  and  sell  products  that  are  substantially  similar  or  identical  to  our  products  or  product
candidates without our permission, and we may not be able to stop them from doing so.

Similar  to  other  biotechnology  companies,  our  patent  position  is  generally  highly  uncertain  and  involves  complex  legal  and  factual
questions. In this regard, we cannot be certain that we or our current or future licensors, licensees, partners or collaborators were the first to
make an invention, or the first inventors to file a patent application claiming an invention in our owned or licensed patents or pending patent
applications. In addition, even if patents are issued, given the amount of time required for the development, testing and regulatory review of
our  product  candidates,  any  patents  protecting  such  candidates  might  expire  before  or  shortly  after  the  resulting  products  are
commercialized. Moreover, the laws and regulations governing patents could change in unpredictable ways that could weaken the ability of
us and our current or future licensors, licensees, partners or collaborators to obtain new patents or to enforce existing patents and patents we
may obtain in the future. In any event, the issuance, scope, validity, enforceability and commercial value of our patent rights and those of our
current or future

64

Table of Contents

licensors, licensees, partners or collaborators are highly uncertain and may not effectively prevent others from commercializing competitive
technologies and products.

In  some  circumstances,  we  may  not  have  the  right  to  control  the  preparation,  filing  and  prosecution  of  patent  applications,  or  to
maintain  or  enforce  the  patents,  covering  technology  that  we  license  from  or  license  to  third  parties  and  may  be  reliant  on  our  current  or
future  licensors,  licensees,  partners  or  collaborators  to  perform  these  activities,  which  means  that  these  patent  applications  may  not  be
prosecuted, and these patents may not be enforced, in a manner consistent with the best interests of our business. If our current or future
licensors, licensees, partners or collaborators fail to establish, maintain, protect or enforce such patents and other intellectual property rights,
such rights may be reduced or eliminated. If our current or future licensors, licensees, partners or collaborators are not fully cooperative or
disagree with us as to the prosecution, maintenance or enforcement of any patent rights, such patent rights could be compromised.

In addition, the legal protection afforded to inventors and owners of intellectual property in countries outside of the United States may
not be as broad or effective as that in the United States and we may be unable to acquire and enforce intellectual property rights outside the
United States to the same extent as in the United States, if at all. Accordingly, our efforts, and those of our licensors, licensees, partners or
collaborators, to enforce intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from
the intellectual property that we own or license.

We do not currently own or have a license to any issued patents that cover our NGM438 product candidate, although NGM438 is
disclosed  and  claimed  in  pending  U.S.  non-provisional  and  international  applications.  Our  NGM707  and  NGM831  product  candidates  are
each covered by one issued U.S. patent, and our NGM621 product candidate is covered by two issued U.S. patents, although the product
and  related  compositions  of  matter  and  methods  of  use  are  disclosed  and  claimed  in  other  pending  U.S.  non-provisional  and/or  national
stage applications in particular foreign countries. The patent landscape surrounding all of our product candidates is crowded, and there can
be no assurance that we will be able to secure patent protection that would adequately cover such product candidates, that we will obtain
sufficiently  broad  claims  to  be  able  to  prevent  others  from  selling  competing  products  or  that  we  will  be  able  to  protect  and  maintain  any
patent protection that we initially secure.

Any changes we make to our product candidates to cause them to have what we view as more advantageous properties may not be
covered by our existing patents and patent applications, and we may be required to file new patent applications and/or seek other forms of
protection for any such altered product candidates. The patent landscape surrounding the technology underlying our product candidates is
crowded, and there can be no assurance that we would be able to secure patent protection that would adequately cover an alternative to any
of our product candidates.

We  may  be  unable  to  obtain  intellectual  property  rights  or  technologies  necessary  to  develop  and  commercialize  our  product
candidates.

Several third parties are actively researching and seeking and obtaining patent protection in the fields of cancer, liver and metabolic
diseases  and  CVM-related  diseases,  including  heart  failure,  and  there  are  issued  third-party  patents  and  published  third-party  patent
applications in these fields. The patent landscape around our product candidates is complex, and we are aware of several third-party patents
and  patent  applications  containing  claims  directed  to  compositions  of  matter,  methods  of  use  and  related  subject  matter,  some  of  which
pertain, at least in part, to subject matter that might be relevant to our product candidates. However, we may not be aware of all third-party
intellectual property rights potentially relating to our product candidates and technologies.

Depending  on  what  patent  claims  ultimately  issue  and  how  courts  construe  the  issued  patent  claims,  as  well  as  the  ultimate
formulation  and  method  of  use  of  our  product  candidates,  we  may  need  to  obtain  a  license  to  practice  the  technology  claimed  in  such
patents.  There  can  be  no  assurance  that  such  licenses  will  be  available  on  commercially  reasonable  terms,  or  at  all.  If  we  are  unable  to
successfully obtain rights to required third-party intellectual property rights or maintain the existing rights to third-party intellectual property
rights  we  have,  we  might  be  unable  to  develop  and  commercialize  one  or  more  of  our  product  candidates,  which  could  have  a  material
adverse effect on our business, financial condition, results of operations and prospects.

We could lose the ability to continue the development and commercialization of our products or product candidates if we breach
any license agreement related to those products or product candidates.

Our  commercial  success  depends  upon  our  ability,  and  the  ability  of  our  current  and  future  licensors,  licensees,  partners  and
collaborators, to develop, manufacture, market and sell our products and product candidates and use our proprietary technologies without
infringing the proprietary rights of third parties. A third party

65

Table of Contents

may hold intellectual property rights, including patent rights that are important or necessary to the development of our products. As a result,
we  are  a  party  to  a  number  of  technology  and  patent  licenses  that  are  important  to  our  business,  and  we  expect  to  enter  into  additional
licenses  in  the  future.  If  we  fail  to  comply  with  the  obligations  under  these  agreements,  including  payment  and  diligence  obligations,  our
licensors  may  have  the  right  to  terminate  these  agreements.  In  the  event  of  a  termination  of  these  agreements,  we  may  not  be  able  to
develop, manufacture, market or sell any product that is covered by these agreements or to engage in any other activities necessary to our
business  that  require  the  freedom-to-operate  afforded  by  the  agreements,  or  we  may  face  other  penalties  under  the  agreements.  For
example, we are party to license agreements with multiple vendors, including our licenses with Horizon Discovery Ltd. and Lonza Sales AG,
under which we license cell lines and other technology used to produce multiple product candidates. We require prior consent from some of
these vendors to grant sub-licenses under these agreements. Therefore, these vendors may be able to prevent us from granting sub-licenses
to  third  parties,  which  could  affect  our  ability  to  use  certain  desired  manufacturers  in  order  to  manufacture  our  product  candidates.  In  the
event of a termination of our license agreements, our ability to manufacture or develop any product candidates covered by these agreements
may be limited or halted unless we can develop or obtain the rights to technology necessary to produce these product candidates.

Any of the foregoing could materially adversely affect the value of the product or product candidate being developed under any such
agreement.  Termination  of  these  agreements  or  reduction  or  elimination  of  our  rights  under  these  agreements  may  result  in  our  having  to
negotiate new or amended agreements, which may not be available to us on equally favorable terms, or at all, or cause us to lose our rights
under these agreements, including our rights to intellectual property or technology important to our development programs.

We  may  become  involved  in  lawsuits  or  other  proceedings  to  protect  or  enforce  our  intellectual  property,  which  could  be
expensive, time-consuming and unsuccessful and have a material adverse effect on the success of our business.

Third parties may infringe patents or misappropriate or otherwise violate intellectual property rights owned or controlled by us or our
current or future licensors, licensees, partners or collaborators. In the future, it may be necessary to initiate legal proceedings to enforce or
defend these intellectual property rights, to protect trade secrets or to determine the validity or scope of intellectual property rights that are
owned or controlled by us or our current or future licensors, licensees, partners or collaborators. Litigation could result in substantial costs
and diversion of management resources, which could harm our business and financial results.

If we or our current or future licensors, licensees, partners or collaborators initiated legal proceedings against a third party to enforce
a patent covering a product candidate, the defendant could counterclaim that such patent is invalid or unenforceable. In patent litigation in
the United States, defendant counterclaims alleging invalidity or unenforceability are commonplace. Grounds for a validity challenge could be
an alleged failure to meet any of several statutory requirements, including lack of novelty, obviousness or non-enablement. Grounds for an
unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld relevant information from
the  United  States  Patent  and  Trademark  Office,  or  USPTO,  or  made  a  misleading  statement  during  prosecution.  In  an  infringement  or
declaratory judgment proceeding, a court may decide that a patent owned by or licensed to us or our current or future licensors, licensees,
partners or collaborators is invalid or unenforceable, or may refuse to stop the other party from using the technology at issue on the grounds
that the patent does not cover the technology in question. An adverse result in any litigation proceeding could put one or more of the patents
at risk of being invalidated, narrowed, held unenforceable or interpreted in such a manner that would not preclude third parties from entering
the market with competing products.

Third  parties  may  initiate  legal  proceedings  against  us  or  our  current  or  future  licensors,  licensees,  partners  or  collaborators  to
challenge  the  validity  or  scope  of  intellectual  property  rights  we  own  or  control.  For  example,  generic  or  biosimilar  drug  manufacturers  or
other competitors or third parties may challenge the scope, validity or enforceability of patents owned or controlled by us or our current or
future  licensors,  licensees,  partners  or  collaborators.  These  proceedings  can  be  expensive  and  time-consuming,  and  many  of  our
adversaries may have the ability to dedicate substantially greater resources to prosecuting these legal actions than us. Accordingly, despite
our efforts, we or our current or future licensors, licensees, partners or collaborators may not be able to prevent third parties from infringing
upon or misappropriating intellectual property rights we own, control or have rights to, particularly in countries where the laws may not protect
those rights as fully as in the United States.

There  is  a  risk  that  some  of  our  confidential  information  could  be  compromised  by  disclosure  during  litigation  because  of  the
substantial amount of discovery required. Additionally, many foreign jurisdictions have rules of discovery that are different than those in the
United States and that may make defending or enforcing our patents extremely difficult. There also could be public announcements of the
results of hearings, motions or other interim

66

Table of Contents

proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have a material adverse effect
on the price of shares of our common stock.

Third-party pre-issuance submission of prior art to the USPTO, opposition, derivation, revocation, reexamination, inter partes review
or interference proceedings, or other pre-issuance or post-grant proceedings, as well as other patent office proceedings or litigation in the
United States or other jurisdictions brought by third parties against patents or patent applications owned or controlled by us or our current or
future  licensors,  licensees,  partners  or  collaborators,  may  be  necessary  to  determine  the  inventorship,  priority,  patentability  or  validity  of
these patents or patent applications. An unfavorable outcome could leave our technology or product candidates without patent protection and
allow third parties to commercialize our technology or product candidates without payment to us. Additionally, potential licensees, partners or
collaborators could be dissuaded from collaborating with us to license, develop or commercialize current or future product candidates if the
breadth or strength of protection provided by our patents and patent applications is threatened. Even if we successfully defend such litigation
or proceeding, we may incur substantial costs and it may distract our management and other employees.

Third parties may initiate legal proceedings against us alleging that we infringe their intellectual property rights or we may initiate
legal proceedings against third parties to challenge the validity or scope of the third-party intellectual property rights, the outcome
of which would be uncertain and could have a material adverse effect on the success of our business.

Third parties may initiate legal proceedings against us or our current or future licensors, licensees, partners or collaborators alleging
that  we  infringe  their  intellectual  property  rights.  Alternatively,  we  may  initiate  legal  proceedings  to  challenge  the  validity  or  scope  of
intellectual property rights controlled by third parties, including in oppositions, interferences, revocations, reexaminations, inter partes review
or  derivation  proceedings  before  the  USPTO  or  its  counterparts  in  other  jurisdictions.  In  this  regard,  we  are  aware  of  several  third-party
patents  and  patent  applications  containing  claims  directed  to  compositions  of  matter,  methods  of  use  and  related  subject  matter,  some  of
which pertain, at least in part, to subject matter that might be relevant to our product candidates. These proceedings can be expensive and
time-consuming,  and  many  of  our  adversaries  may  have  the  ability  to  dedicate  substantially  greater  resources  to  prosecuting  these  legal
actions than us.

In  addition,  we  may  be  subject  to  claims  that  we  or  our  employees  have  used  or  disclosed  confidential  information  or  intellectual
property,  including  trade  secrets  or  other  proprietary  information,  of  any  such  employee’s  former  employer,  or  that  third  parties  have  an
interest in our patents as an inventor or co-inventor. Likewise, we and our current or future licensors, licensees, partners or collaborators may
be subject to claims that former employees, partners, collaborators or other third parties have an interest in our owned or in-licensed patents,
trade secrets or other intellectual property as an inventor or co-inventor. Litigation may be necessary to defend against these claims.

Even if we believe third-party intellectual property claims are without merit, there is no assurance that a court would find in our favor
on questions of infringement, validity, enforceability or priority. In order to successfully challenge the validity of any such U.S. patent in federal
court, we would need to overcome a presumption of validity in favor of the granted third-party patent. This is a high burden, requiring us to
present clear and convincing evidence as to the invalidity of any such U.S. patent claim.

An  unfavorable  outcome  in  any  such  proceeding  could  require  us  and  our  current  or  future  licensors,  licensees,  partners  or
collaborators  to  cease  using  the  related  technology  or  developing  or  commercializing  the  product  or  product  candidate,  or  to  attempt  to
license rights to it from the prevailing party, which may not be available on commercially reasonable terms, or at all. Additionally, we could be
found liable for monetary damages, including treble damages and attorneys’ fees, if we are found to have willfully infringed a patent. A finding
of infringement could prevent us from commercializing our product candidates or force us to cease some of our business operations, which
could materially harm our business.

We may not be able to protect our intellectual property rights throughout the world.

Filing, prosecuting and defending patents in all countries throughout the world would be prohibitively expensive, and our intellectual
property rights in some countries outside the United States can be less extensive than those in the United States. In addition, the laws of
some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the United States, even in
jurisdictions  where  we  do  pursue  patent  protection.  Consequently,  we  may  not  be  able  to  prevent  third  parties  from  practicing  our  or  our
licensors’ inventions in all countries outside the United States, even in jurisdictions where we or our licensors do pursue patent protection.
Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own competing products
and, further, may export otherwise infringing products to territories where we have patent protection, but enforcement is not as strong as that
in the United States.

67

Table of Contents

Many countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In
addition, many countries limit the enforceability of patents against government agencies or government contractors. In these countries, the
patent owner may have limited remedies, which could materially diminish the value of such patent. If we are forced to grant a license to third
parties with respect to any patents relevant to our business, our competitive position may be impaired, and our business, financial condition,
results of operations and prospects may be adversely affected.

The complexity and uncertainty of European patent laws have increased in recent years. In Europe, the new unitary patent system
that came into effect in 2023 would significantly impact European patents, including those granted before the introduction of such a system.
Under the unitary patent system, European applications will have the option, upon grant of a patent, of becoming a Unitary Patent which will
be subject to the jurisdiction of the Unitary Patent Court, or UPC. As the UPC is a new court system, there is no precedent for the court,
increasing  the  uncertainty  of  any  litigation.  Patents  that  remain  under  the  jurisdiction  of  the  UPC  will  be  potentially  vulnerable  to  a  single
UPC-based revocation challenge that, if successful, could invalidate the patent in all countries who are signatories to the UPC. We cannot
predict with certainty the long-term effects of any potential changes.

Risks Related to Ownership of Our Common Stock

We have in the past and may in the future fail to continue to meet the listing standards of Nasdaq, and as a result our common
stock may be delisted, which could have a material adverse effect on the liquidity of our common stock.

Our  common  stock  currently  trades  on  The  Nasdaq  Global  Select  Market.  The  Nasdaq  Stock  Market  LLC,  or  Nasdaq,  has
requirements that a company must meet in order to remain listed on Nasdaq. On December 1, 2023, we received a letter from the Listing
Qualifications Staff, or the Nasdaq Staff, of Nasdaq notifying us that for the last 30 consecutive business days, the bid price of our common
stock had closed below $1.00 per share, the minimum closing bid price required by Nasdaq's continued listing requirements. The notification
had no immediate effect on the listing of our common stock on The Nasdaq Global Select Market. In accordance with Nasdaq requirements,
we  had  a  period  of  180  calendar  days,  or  until  May  29,  2024,  or  the  Compliance  Date,  to  regain  compliance  with  the  minimum  bid  price
requirement. On January 18, 2024, we received a letter from Nasdaq notifying us that the closing bid price of our common stock had been at
$1.00 per share or greater for 10 consecutive business days, from January 2, 2024 to January 17, 2024, and accordingly, we had regained
compliance  with  Nasdaq  Listing  Rule  5450(a)(1).  There  can  be  no  assurance  that  we  will  continue  to  meet  the  minimum  bid  price
requirement,  or  any  other  Nasdaq  requirements,  in  the  future.  In  addition,  we  may  be  unable  to  meet  other  applicable  Nasdaq  listing
requirements,  including  maintaining  minimum  levels  of  stockholders’  equity  or  market  values  of  our  common  stock,  in  which  case  our
common stock could be delisted.

If we remain a public company and our common stock were to be delisted from Nasdaq, we could face significant material adverse

consequences, including:

•

•

•

•

•

•

a limited availability of market quotations for our common stock;

a reduced amount of news and analyst coverage for our company;

a decreased ability to issue additional securities or obtain additional financing in the future;

reduced liquidity for our stockholders;

potential loss of confidence by partners and employees; and

loss of institutional investor interest and fewer business development opportunities.

The market price of our common stock has been and may continue to be volatile, and you could lose all or part of your investment.

The market price for our common stock has fluctuated significantly from time to time, for example, varying between a high of $32.12
on March 17, 2021 and a low of $0.60 on November 16, 2023. The trading price of our common stock has been and may continue to be
highly  volatile  and  subject  to  wide  fluctuations  in  response  to  various  factors,  some  of  which  we  cannot  control.  In  addition  to  the  factors
discussed in this “Risk Factors” section, these factors include:

•

•

our failure to complete the Offer and the Merger within the expected time frame, or at all;

interim or final results of clinical trials of our product candidates or those of our competitors;

Table of Contents

•

•

•

•

•

•

•

•

•

our  ability  to  raise  adequate  capital  through  public  or  private  equity  or  debt  offerings  or  negotiate  potential  BD  Arrangements  in  a
timely manner or at all, particularly in light of restrictions imposed on such activities under the Merger Agreement;

the success of competitive products or technologies;

regulatory actions with respect to our product candidates or our competitors’ product candidates or products;

timeline delays in our clinical trials;

the level of expenses related to any of our product candidates or clinical development programs;

actual or anticipated changes in our growth rate relative to our competitors;

announcements  by  us  or  our  competitors  or  partners  of  significant  acquisitions,  strategic  collaborations,  joint  ventures  or  capital
commitments;

regulatory, legal or payor developments in the United States and other countries;

developments or disputes concerning patent applications, issued patents or other proprietary rights;

the recruitment or departure of key personnel;

the results of our efforts to in-license or acquire additional product candidates or products;

actual or anticipated changes in estimates as to financial results, development timelines or recommendations by securities analysts;

variations in our financial results or those of companies that are perceived to be similar to us;

fluctuations in the valuation of companies perceived by investors to be comparable to us;

share price and volume fluctuations attributable to inconsistent trading volume levels of our shares;

announcement or expectation of financing efforts;

purchases or sales of our common stock by us, our insiders or our other stockholders;

changes in the structure of healthcare payment systems;

• market conditions in the pharmaceutical and biotechnology sectors; and

•

general economic, industry and market conditions.

In  addition,  the  stock  market  in  general,  and  The  Nasdaq  Global  Select  Market  and  biotechnology  companies  in  particular,  have
experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these
companies,  including  in  connection  with  ongoing  global  geopolitical  conflicts,  which  has  resulted  in  decreased  stock  prices  for  many
companies notwithstanding the lack of a fundamental change in their underlying business models or prospects. Broad market and industry
factors, including worsening economic conditions and other adverse effects or developments relating to the effects of potential future bank
failures,  macroeconomic  factors  including  inflation  and  elevated  interest  rates,  and  global  geopolitical  conflicts  may  negatively  affect  the
market  price  of  our  common  stock,  regardless  of  our  actual  operating  performance.  The  realization  of  any  of  the  above  risks  or  any  of  a
broad range of other risks, including those described elsewhere in this “Risk Factors” section, could have a dramatic and material adverse
impact on the market price of our common stock.

Because of volatility in our trading price and trading volume, we may incur significant costs from class action securities litigation.

Holders of stock in companies that have a volatile stock price frequently bring securities class action litigation against the company
that issued the stock. We may be the target of this type of litigation in the future. If any of our stockholders were to bring a lawsuit of this type
against  us,  even  if  the  lawsuit  is  without  merit,  we  could  incur  substantial  costs  defending  the  lawsuit  and  the  time  and  attention  of  our
management could be diverted from other business concerns, either of which could seriously harm our business. Refer to the risk factors
titled “An active trading market for our common stock may not be sustained and sales of a substantial number of shares of our common stock
in the public market could cause our stock price to fall” and "We may become involved in securities class action litigation due to the Offer and
the Merger that could divert management’s attention and harm our business, and adversely affect our ability to consummate the Offer and
the Merger within the expected time frame or at all."

Our  principal  stockholders,  including  entities  affiliated  with  The  Column  Group,  Merck  and  management,  own  a  substantial
percentage of our stock and collectively will be able to exert significant control over matters subject to stockholder approval.

As  of  December  28,  2023,  David  V.  Goeddel,  Ph.D.,  a  member  of  our  board  of  directors,  and  entities  affiliated  with  The  Column
Group, collectively referred to as TCG, collectively beneficially owned approximately 26.7% of our common stock and, as a result, have the
ability to significantly influence all matters submitted to our stockholders for approval at a meeting of our stockholders, including the approval
of any significant transaction. On December 28, 2023, we received a letter from TCG which expressed TCG's intent to explore and evaluate
a  potential  acquisition  of  all  of  our  outstanding  shares  of  common  stock  not  already  owned  by  TCG  in  a  going  private  transaction.  We
subsequently executed the Merger Agreement with Parent and Merger Sub, each of which TCG is the controlling stockholder and with which
Dr.  Goeddel  is  affiliated  (although  Dr.  Goeddel  recused  himself  from  the  board  of  directors’  determination  in  favor  of  the  Merger).  With
respect to the Offer and the Merger, although TCG has the ability to significantly influence matters submitted to our stockholders for approval
at  a  meeting  of  our  stockholders,  the  consummation  of  the  Offer  is  subject  to  the  condition  that  at  least  a  majority  of  our  stockholders
unaffiliated with TCG and certain other parties elect to tender their shares in the Offer.

Additionally,  our  executive  officers,  directors,  significant  stockholders,  including  TCG  and  Merck  and  their  respective  affiliates,
collectively beneficially own a substantial amount of our voting stock. These stockholders collectively may be able to determine all matters
requiring stockholder approval at a meeting of our stockholders. For example, these stockholders collectively may be able to control elections
of directors, amendments of our organizational documents or approval of any merger, sale of assets or other major corporate transaction.
The interests of this group of stockholders may not always coincide with your interests or the interests of other stockholders, particularly as it
relates to TCG and the Offer and the Merger. In addition, if any of our significant stockholders decide to sell a meaningful amount of their
ownership position and there is not sufficient demand in the market for our common stock, our stock price could fall.

We  are  a  “smaller  reporting  company”  and  the  reduced  disclosure  requirements  applicable  to  such  companies  that  we  have
availed ourselves of may make our common stock less attractive to investors.

We are currently a “smaller reporting company” as defined in the Exchange Act. We will be a smaller reporting company and may
take advantage of the scaled-back disclosures available to smaller reporting companies for so long as (i) the market value of our voting and
non-voting ordinary shares held by non-affiliates is less than $250.0 million measured on the last business day of our second fiscal quarter or
(ii) (a) our annual revenue is less than $100.0 million during the most recently completed fiscal year and (b) the market value of our voting
and  non-voting  ordinary  shares  held  by  non-affiliates  is  less  than  $700.0  million  measured  on  the  last  business  day  of  our  second  fiscal
quarter.

As a smaller reporting company, we are permitted to comply with scaled-back disclosure obligations in our SEC filings compared to
other issuers, including with respect to disclosure obligations regarding executive compensation in our periodic reports and proxy statements.
We  have  elected  to  adopt  certain  of  the  accommodations  available  to  smaller  reporting  companies,  including  but  not  limited  to  reduced
disclosure obligations regarding executive compensation arrangements.

Until we cease to be a smaller reporting company, the scaled-back disclosure in our SEC filings will result in less information about
our  company  being  available  than  for  other  public  companies.  If  investors  consider  our  common  stock  less  attractive  as  a  result  of  our
election to use certain of the scaled-back disclosure permitted for smaller reporting companies, there may be a less active trading market for
our common stock and our share price may be more volatile.

An active trading market for our common stock may not be sustained and sales of a substantial number of shares of our common
stock in the public market could cause our stock price to fall.

Our common stock is currently listed on The Nasdaq Global Select Market under the symbol “NGM” and trades on that market. We
cannot  ensure  that  an  active  trading  market  for  our  common  stock  will  be  sustained.  Accordingly,  we  cannot  ensure  the  liquidity  of  any
trading market, your ability to sell your shares of our common stock when desired or the prices that you may obtain for your shares.

For the trading days during the three months ended December 31, 2023, the average daily trading volume for our common stock on
The Nasdaq Global Select Market was only 481,473 shares. As a result, sales of a substantial number of shares of our common stock in the
public market, including pursuant to the Amended Sales Agreement, or by any of our large stockholders, or even the perception in the market
that we or the holders of a large number of shares intend to sell shares, could reduce the market price of our common stock. In addition, as a

70

Table of Contents

result  of  the  low  trading  volume  of  our  common  stock,  the  trading  of  relatively  small  quantities  of  shares  by  our  stockholders  could
disproportionately influence the market price of our common stock in either direction. The price for our shares could, for example, decline
significantly  in  the  event  that  a  large  number  of  shares  of  our  common  stock  are  sold  on  the  market  without  commensurate  demand,  as
compared  to  an  issuer  with  a  higher  trading  volume  that  could  better  absorb  those  sales  without  an  adverse  impact  on  its  stock  price.
Moreover, certain holders of our common stock have rights, subject to certain conditions, to require us to file registration statements covering
their shares or to include their shares in registration statements that we may file for ourselves or other stockholders.

We do not intend to pay dividends on our common stock so any returns will be limited to the value of our stock.

We currently anticipate that we will retain future earnings for the development, operation and expansion of our business and do not
anticipate  declaring  or  paying  any  cash  dividends  for  the  foreseeable  future.  Any  return  to  stockholders  will  therefore  be  limited  to  the
appreciation of their stock, if any.

Some  provisions  of  our  charter  documents  and  Delaware  law  may  have  anti-takeover  effects  or  could  otherwise  discourage  an
acquisition of us by others, even if an acquisition would benefit our stockholders, and may prevent attempts by our stockholders
to replace or remove our current management.

Provisions  in  our  amended  and  restated  certificate  of  incorporation  and  amended  and  restated  bylaws,  as  well  as  provisions  of
Delaware law, could make it more difficult for a third party to acquire us or increase the cost of acquiring us, even if doing so would benefit
our stockholders, or to remove our current management. These provisions include:

•

•

•

•

•

•

a  board  of  directors  divided  into  three  classes  serving  staggered  three-year  terms,  such  that  not  all  members  of  the  board  will  be
elected at one time;

authorizing the issuance of “blank check” preferred stock, the terms of which we may establish and shares of which we may issue
without stockholder approval;

prohibiting cumulative voting in the election of directors, which would otherwise allow for less than a majority of stockholders to elect
director candidates;

prohibiting  stockholder  action  by  written  consent,  thereby  requiring  all  stockholder  actions  to  be  taken  at  a  meeting  of  our
stockholders;

eliminating the ability of stockholders to call a special meeting of stockholders; and

establishing advance notice requirements for nominations for election to the board of directors or for proposing matters that can be
acted upon at stockholder meetings.

These  provisions  may  frustrate  or  prevent  any  attempts  by  our  stockholders  to  replace  or  remove  our  current  management  by
making it more difficult for stockholders to replace members of our board of directors, who are responsible for appointing the members of our
management.  Because  we  are  incorporated  in  Delaware,  we  are  governed  by  the  provisions  of  Section  203  of  the  Delaware  General
Corporation Law which may discourage, delay or prevent someone from acquiring us or merging with us whether or not it is desired by or
beneficial  to  our  stockholders.  In  addition,  Section  203  of  the  Delaware  General  Corporation  Law  prohibits  a  publicly-held  Delaware
corporation  from  engaging  in  a  business  combination  with  an  interested  stockholder,  which  is  generally  a  person  that  together  with  its
affiliates owns, or within the last three years has owned, 15% of our voting stock, for a period of three years after the date of the transaction
in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner.

Any provision of our amended and restated certificate of incorporation, amended and restated bylaws or Delaware law that has the
effect of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our
common stock, and could also affect the price that some investors are willing to pay for our common stock.

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware and the federal
district  courts  of  the  United  States  will  be  the  exclusive  forum  for  substantially  all  disputes  between  us  and  our  stockholders,
which  could  limit  our  stockholders’  ability  to  obtain  a  favorable  judicial  forum  for  disputes  with  us  or  our  directors,  officers  or
employees.

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive
forum for the following types of actions or proceedings under Delaware statutory or common law: any derivative action or proceeding brought
on our behalf; any action asserting a breach of a fiduciary

71

Table of Contents

duty  owed  by  any  director,  officer  or  other  employee  to  us  or  our  stockholders;  any  action  asserting  a  claim  against  us  or  any  director  or
officer or other employee arising pursuant to the Delaware General Corporation Law, our amended and restated certificate of incorporation or
our amended and restated bylaws; any action with respect to the validity of our amended and restated certificate of incorporation or amended
and restated bylaws; any action as to which the Delaware General Corporation Law confers jurisdiction to the Court of Chancery of the State
of Delaware; or any action asserting a claim against us or any director or officer or other employee that is governed by the internal affairs
doctrine. This provision would not apply to suits brought to enforce a duty or liability created by the Securities and Exchange Act of 1934, as
amended, or the Exchange Act, or any other claim for which the federal courts have exclusive jurisdiction. Furthermore, Section 22 of the
Securities Act of 1933, as amended, or the Securities Act, creates concurrent jurisdiction for federal and state courts over all such Securities
Act  actions.  Accordingly,  both  state  and  federal  courts  have  jurisdiction  to  entertain  such  claims.  To  prevent  having  to  litigate  claims  in
multiple  jurisdictions  and  the  threat  of  inconsistent  or  contrary  rulings  by  different  courts,  among  other  considerations,  our  amended  and
restated certificate of incorporation further provides that the federal district courts of the United States will be the exclusive forum for resolving
any complaint asserting a cause of action arising under the Securities Act. While the Delaware courts have determined that such choice of
forum  provisions  are  facially  valid,  a  stockholder  may  nevertheless  seek  to  bring  a  claim  in  a  venue  other  than  those  designated  in  the
exclusive  forum  provisions.  In  such  instance,  we  would  expect  to  vigorously  assert  the  validity  and  enforceability  of  the  exclusive  forum
provisions  of  our  amended  and  restated  certificate  of  incorporation.  This  may  require  significant  additional  costs  associated  with  resolving
such action in other jurisdictions and there can be no assurance that the provisions will be enforced by a court in those other jurisdictions.

These  exclusive  forum  provisions  may  limit  a  stockholder’s  ability  to  bring  a  claim  in  a  judicial  forum  that  it  finds  favorable  for
disputes with us or our directors, officers or other employees, which may discourage lawsuits against us and our directors, officers and other
employees. If a court were to find either exclusive-forum provision in our amended and restated certificate of incorporation to be inapplicable
or unenforceable in an action, we may incur further significant additional costs associated with resolving the dispute in other jurisdictions, all
of which could seriously harm our business.

General Risk Factors

We,  our  CROs,  our  CMOs,  our  current  and  potential  future  partners  and  other  third  parties  we  rely  on  or  partner  with  could
experience a cybersecurity incident that could harm our business.

We  collect,  store  and  transmit  proprietary,  confidential  and  sensitive  information,  including  personal  information  (such  as  health-
related data), in the course of our business. Our technology systems and the information and data processed and stored in our technology
systems or otherwise by us or on our behalf, and the technology systems of, and data accessed on our behalf by, our research collaborators,
partners, CROs, CMOs, contractors, consultants and other third parties on which we depend to operate our business, may be vulnerable to
security breaches, loss, damage, corruption, unauthorized access, use or disclosure or misappropriation. Such incidents may result from the
actions  of  a  wide  variety  of  actors,  including  traditional  hackers,  our  personnel  or  the  personnel  of  the  third  parties  we  work  with,
sophisticated nation-states and nation-state-supported actors. During times of war and other major conflicts, we, the third parties upon which
we rely, and our customers may be vulnerable to a heightened risk of these attacks, including retaliatory cyberattacks, that could materially
disrupt our systems and operations, supply chain, and ability to produce, sell and distribute our goods and services. Threats we and third
parties on which we rely may face are constantly evolving and include (without limitation) malware, viruses, software vulnerabilities and bugs,
software  or  hardware  failure,  hacking,  denial  of  service  attacks,  social  engineering  (including  phishing),  ransomware,  inside  threats,
credential  stuffing  or  other  cyberattacks,  telecommunications  failures,  earthquakes,  fires,  floods  and  similar  threats.  Threats  such  as
ransomware attacks, for example, are becoming increasingly prevalent and severe. Extortion payments may alleviate the negative impact of
a  ransomware  attack,  but  we  may  be  unwilling  or  unable  to  make  such  payments  due  to,  for  example,  applicable  laws  or  regulations
prohibiting such payments. Supply-chain attacks have also increased in frequency and severity, and we cannot guarantee that third parties’
infrastructure in our supply chain or our third-party partners’ supply chains have not been compromised. Our ability to monitor third parties on
whom we rely to operate our business is limited, and these third parties may be subject to, and may expose us to, cyberattacks and other
security incidents.

We may, under certain data privacy and security obligations, be required to, or we may choose to, expend significant resources or
modify our business activities (including our clinical trial activities) in an effort designed to protect against security incidents. While we have
developed systems and processes designed to protect the integrity, confidentiality and security of the confidential and personal information
under our control, we cannot assure you that any security measures that we or our third-party service providers implement will be effective in

72

Table of Contents

preventing  cybersecurity  incidents.  There  are  many  different  cyber-crime  and  hacking  techniques,  and  as  such  techniques  continue  to
evolve,  we  may  be  unable  to  anticipate  attempted  security  breaches,  identify  them  before  our  information  is  exploited  or  react  in  a  timely
manner.

Some of our workforce work remotely on a full- or part-time basis outside of our corporate network security protection boundaries or
otherwise  utilize  network  connections,  computers  and  devices  outside  of  our  premises  or  network,  which  imposes  additional  risks  to  our
business,  including  increased  risk  of  industrial  espionage,  phishing  and  other  cybersecurity  attacks,  and  unauthorized  dissemination  of
proprietary or confidential information, including personal information, any of which could have a material adverse effect on our business.

Despite  our  efforts  to  strengthen  security  and  authentication  measures,  we  have  not  always  been  able  in  the  past,  and  may  be
unable  in  the  future,  to  detect  vulnerabilities  in  our  information  technology  systems.  We  have  experienced  an  overall  increase  in
cybersecurity incidents since 2020, none of which, to date, have caused material disruption to our business, or, to our knowledge, involved a
material  security  breach.  We  or  the  third  parties  we  rely  on  or  partner  with  could  experience  a  material  system  failure,  security  breach  or
other  cybersecurity  incident,  including  any  related  to  or  in  connection  with  any  of  the  aforementioned  threats,  in  the  future,  which  could
interrupt  our  operations,  disrupt  our  development  programs  and  have  a  material  adverse  effect  on  our  business,  financial  condition  and
results of operations. For example, the loss or corruption of clinical trial data from completed or future clinical trials could result in delays in
our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. Likewise, we rely on third parties for the
manufacture of our product candidates, to analyze clinical trial samples and to conduct clinical trials, and cybersecurity incidents experienced
by these third parties could have a material adverse effect on our business. Security breaches and other cybersecurity incidents affecting us
or the third parties we rely on or partner with could also result in substantial remediation costs and expose us to litigation (including class
claims),  regulatory  enforcement  action  (for  example,  investigations,  fines,  penalties,  audits  and  inspections),  additional  reporting
requirements and/or oversight, fines, penalties, indemnification obligations, negative publicity, reputational harm, monetary fund diversions,
interruptions in our operations (including availability of data), financial loss and other liabilities and harms. Additionally, such incidents may
trigger  data  privacy  and  security  obligations  requiring  us  to  notify  relevant  stakeholders  or  to  publicly  disclose  material  breaches  when
required under securities and other laws and regulations. These disclosures are costly, and the disclosures or the failure to comply with such
requirements could lead to adverse consequences.

Our contracts may not contain limitations of liability, and even where they do, there can be no assurance that limitations of liability in
our contracts are sufficient to protect us from claims related to our data privacy and security obligations. Additionally, we cannot be certain
that our insurance coverage will be adequate for data security liabilities actually incurred, will continue to be available to us on economically
and commercially reasonable terms, or at all, or that any insurer will not deny coverage as to any future claim. The successful assertion of
one  or  more  large  claims  against  us  that  exceed  available  insurance  coverage,  or  the  occurrence  of  changes  in  our  insurance  policies,
including  premium  increases  or  the  imposition  of  large  deductible  or  co-insurance  requirements,  could  adversely  affect  our  reputation,
business, financial condition and results of operations.

We are subject to rapidly changing and increasingly stringent foreign and domestic laws and regulations relating to privacy, data
protection and information security. The restrictions imposed by these requirements or our actual or perceived failure to comply
with them could harm our business.

We may collect, use, transfer or otherwise process proprietary, confidential and sensitive information, including personal information
(including health-related data), which subjects us to numerous evolving and complex data privacy and security obligations, including various
laws,  regulations,  guidance,  industry  standards,  external  and  internal  privacy  and  security  policies,  contracts  and  other  obligations  that
govern the processing of such information by us and on our behalf. Outside the United States, an increasing number of laws, regulations,
and industry standards may govern data privacy and security. For example, the European Union’s General Data Protection Regulation, or EU
GDPR,  and  the  United  Kingdom’s  GDPR,  or  UK  GDPR,  collectively  the  GDPR,  impose  strict  requirements  for  processing  personal
information. The GDPR, together with other relevant laws that govern patient confidentiality and storage of personal health data, may apply
to our processing of personal information from clinical trials participants and other individuals located in the EEA and/or the United Kingdom,
or  UK,  and,  if  any  of  our  product  candidates  are  approved,  we  may  seek  to  commercialize  those  products  in  the  EEA  and/or  the  UK  (as
applicable).  Companies  that  violate  the  GDPR  can  face  private  litigation,  prohibitions  on  data  processing,  other  administrative  measures,
reputational damage and fines of up to the greater of 20 million Euros under the EU GDPR, 15.5 million pounds sterling under the UK GDPR,
or, in each case, 4% of their worldwide annual revenue. The GDPR requires us to, among other things: give detailed disclosures about how
we  collect,  use  and  share  personal  information;  contractually  commit  to  data  protection  measures  in  our  contracts  with  vendors;  maintain
adequate data security measures; notify regulators and affected individuals of certain data breaches; meet

73

Table of Contents

extensive  privacy  governance  and  documentation  requirements;  and  honor  individuals’  data  protection  rights,  including,  but  not  limited  to,
their rights to access, correct and delete their personal information.

On  July  10,  2023,  the  European  Commission  adopted  an  adequacy  decision  for  the  new  EU-US  Data  Privacy  Framework,  which
facilitates international transfers of personal data between the EU and the US for companies that choose to self-certify with the framework
and comply with its principles. However, the EU-US Data Privacy Framework is expected to be subject to legal challenges and there is no
assurance that we can satisfy or rely on this mechanism to lawfully transfer personal data to the United States.

On June 28, 2021, the European Commission adopted an adequacy decision permitting flows of personal data between the EU and
the  UK  to  continue  without  additional  requirements.  The  UK  Government  also  adopted  a  reciprocal  adequacy  decision  in  respect  of  EEA
member states permitting flows of personal data from the UK to the EEA. However, the European Commission's UK adequacy decision will
automatically  expire  in  June  2025  unless  the  European  Commission  re-assesses  and  renews/extends  that  decision  and  remains  under
review by the European Commission during this period. The UK adequacy decision could be withdrawn prior to June 2025, for example, if the
legal  framework  of  the  UK  GDPR  diverges  from  the  EU  GDPR  in  a  way  that  impacts  the  deemed  adequacy  of  the  UK  GDPR,  if  the  UK
permits cross-border data transfers to third countries that do not currently have an EU adequacy decision without requiring sufficient privacy
protections, or if the UK adequacy decision is successfully challenged at the European Court of Justice. If the UK adequacy decision were to
be withdrawn, personal data could not flow freely between the UK and the EU and additional safeguards would need to be adopted, which
could result in additional costs for us.

The relationship between the UK and the EU in relation to certain aspects of data protection laws remains unclear, and it is unclear
how UK data protection laws and regulations will develop in the medium to longer term, and how data transfers to and from the UK will be
regulated in the long term. The UK’s Data Protection and Digital Information Bill, or the Bill, was re-introduced before the UK Parliament in
March 2023, proposing reforms intended to update and simplify the UK’s data protection framework, which may deviate from the EU GDPR.

Certain  jurisdictions  have  enacted  data  localization  laws  and  laws  restricting  cross-border  transfers  of  personal  information.  In
particular,  regulators  and  courts  in  the  EEA  and  the  UK  have  in  the  past  significantly  restricted  the  transfer  of  personal  information  to  the
United States and other countries whose privacy laws it believes are inadequate, and may do so again in the future. Other jurisdictions may
adopt  similarly  stringent  interpretations  of  their  data  localization  and  cross-border  data  transfer  laws.  Although  there  are  currently  various
mechanisms that may be used to transfer personal information from the EEA and UK to the United States in compliance with law, including
without limitation the EEA’s standard contractual clauses and the UK's international data transfer agreement, these mechanisms are subject
to legal challenges, and there is no assurance that we can satisfy or rely on these measures to lawfully transfer personal information to the
United States.

We  continue  to  monitor  changes  in  data  protection  laws  related  to  the  cross-border  transfer  of  personal  information;  however,
uncertainty remains regarding any future regulations, interpretations of existing law or guidance that may be issued, particularly by the EU
authorities.  If  we  are  unable  to  implement  a  valid  compliance  solution  for  cross-border  transfers  of  personal  information,  or  if  the
requirements for a legally-compliant transfer are too onerous, we will face increased exposure to significant adverse consequences, including
substantial  fines,  regulatory  actions,  as  well  as  injunctions  against  the  export  and  processing  of  personal  information  from  the  EEA.  Our
inability  to  import  personal  information  from  the  EEA,  UK  or  Switzerland  or  other  countries  may  also  restrict  or  prohibit  our  clinical  trial
activities  in  those  countries;  limit  our  ability  to  collaborate  with  CROs,  service  providers,  contractors  and  other  companies  subject  to  laws
restricting cross-border data transfers; require us to increase our data processing capabilities in other countries at significant expense and
may  otherwise  negatively  impact  our  business  operations.  We  may  also  become  subject  to  new  laws  in  these  jurisdictions  that  regulate
cybersecurity and non-personal data, such as data collected through the internet of things. Depending on how these laws are interpreted, we
may have to make changes to our business practices and products to comply with such obligations.

Additionally,  other  countries  have  enacted  or  are  considering  enacting  similar  cross-border  data  transfer  restrictions  and  laws

requiring local data residency, which could increase the cost and complexity of delivering our services and operating our business.

Privacy  and  data  security  laws  in  the  United  States  at  the  federal,  state  and  local  level  are  increasingly  complex  and  changing
rapidly. For example, at the federal level, HIPAA, as amended by HITECH, imposes specific requirements relating to the privacy, security and
transmission  of  individually  identifiable  health  information.  Additionally,  at  the  state  level,  the  privacy  and  data  protection  landscape  is
changing  rapidly.  For  example,  the  California  Consumer  Privacy  Act  of  2018,  or  CCPA,  took  effect  on  January  1,  2020.  The  CCPA  gives
California residents certain rights similar to the individual rights given under the GDPR, including the right to access and

74

Table of Contents

delete their personal information, opt-out of certain personal information sharing and receive detailed information about how their personal
information is used. The CCPA provides for civil penalties for violations, including statutory fines for noncompliance and a limited private right
of action in connection with certain data breaches. In addition, the California Privacy Rights Act of 2020, or CPRA, which became operative
January  1,  2023,  expands  the  CCPA’s  requirements,  including  in  that  it  applies  to  personal  information  of  business  representatives  and
employees and establishes a new regulatory agency to implement and enforce the law. While the CCPA contains an exemption for certain
personal information processed in connection with clinical trials, we may process other personal information that is subject to the CCPA and
CPRA. Other states, such as Virginia, Connecticut, Utah and Colorado, have also passed comprehensive privacy laws, and similar laws are
being  considered  in  several  other  states,  as  well  as  at  the  federal  and  local  levels.  The  evolving  patchwork  of  differing  state  and  federal
privacy and data security laws increases the cost and complexity of operating our business and increase our exposure to liability.

We may also be bound by contractual obligations related to data privacy and security, and our efforts to comply with such obligations
may  not  be  successful.  We  may  publish  privacy  policies,  marketing  materials  and  other  statements,  such  as  compliance  with  certain
certifications  or  self-regulatory  principles,  regarding  data  privacy  and  security.  If  these  policies,  materials  or  statements  are  found  to  be
deficient,  lacking  in  transparency,  deceptive,  unfair  or  misrepresentative  of  our  practices,  we  may  be  subject  to  investigation,  enforcement
actions by regulators or other adverse consequences.

Our obligations related to data privacy and security are quickly changing in an increasingly stringent fashion. These obligations may
be  subject  to  differing  applications  and  interpretations,  which  may  be  inconsistent  or  in  conflict  among  jurisdictions.  Preparing  for  and
complying  with  these  obligations  requires  us  to  devote  significant  resources  (including,  without  limitation,  financial  and  time-related
resources).  These  obligations  may  necessitate  changes  to  our  information  technologies,  systems  and  practices  and  to  those  of  any  third
parties  that  process  personal  information  on  our  behalf.  In  addition,  these  obligations  may  require  us  to  change  aspects  of  our  business
model. Although we endeavor to comply with applicable data privacy and security obligations, we may at times fail (or be perceived to have
failed) to do so. Moreover, despite our efforts, our personnel or third parties upon whom we rely, may fail to comply with such obligations,
which could impact whether or not we are in compliance.

If  we  (or  third  parties  on  which  we  rely)  fail,  or  are  perceived  to  have  failed,  to  address  or  comply  with  data  privacy  and  security
obligations,  we  could  face  significant  consequences,  including  (without  limitation):  government  or  regulatory  enforcement  actions  (e.g.,
investigations,  fines,  penalties,  audits,  inspections  and  similar);  litigation  (including  class-related  claims);  additional  reporting  requirements
and/or oversight; bans on processing personal information; orders to destroy or not use personal information; and imprisonment of company
officials. Any of these events could have a material adverse effect on our reputation, business or financial condition, including but not limited
to: loss of customers; interruptions or stoppages in our business operations (including clinical trials); inability to process personal information
or to operate in certain jurisdictions; limiting our ability to develop or commercialize our products; expenditure of time and resources to defend
any claim or inquiry; adverse publicity; or revision or restructuring of our operations.

Our  operations  are  vulnerable  to  interruption  by  fire,  earthquake,  power  loss,  telecommunications  failure,  terrorist  activity  and
other events beyond our control, which could harm our business.

Our facilities have experienced electrical blackouts as a result of a shortage of available electrical power. Future blackouts, which
may be implemented by the local electricity provider in the face of high winds and dry conditions, could disrupt our operations. Our facility is
located  in  a  seismically  active  region.  We  have  not  undertaken  a  systematic  analysis  of  the  potential  consequences  to  our  business  and
financial results from a major earthquake, fire, power loss, terrorist activity or other disasters and do not have a comprehensive recovery plan
for such disasters. In addition, we do not carry sufficient insurance to compensate us for actual losses from interruption of our business that
may occur, and any losses or damages incurred by us could harm our business. The sole supplier of some of our clinical drug substances is
located  in  Lithuania,  a  region  that  has  experienced  political  unrest.  Refer  to  the  risk  factor  titled  “We  rely  completely  on  CMOs  for  the
manufacture of our product candidates and are subject to many manufacturing risks, any of which could substantially increase our costs and
limit supply of our product candidates and any future products.” If our operations or the operations of third parties providing services to us are
disrupted by any such occurrences, our business and future prospects may be negatively affected.

We use and generate materials that may expose us to material liability.

Our research programs involve the use of hazardous materials, chemicals and radioactive and biological materials. We are subject to

foreign, federal, state and local environmental and health and safety laws and

75

regulations  governing,  among  other  matters,  the  use,  manufacture,  handling,  storage  and  disposal  of  hazardous  materials  and  waste
products. We may incur significant costs to comply with these current or future environmental and health and safety laws and regulations. In
addition,  we  cannot  completely  eliminate  the  risk  of  contamination  or  injury  from  hazardous  materials  and  may  incur  material  liability  as  a
result of such contamination or injury. In the event of an accident, an injured party may seek to hold us liable for any damages that result. Any
liability could exceed the limits or fall outside the coverage of our workers’ compensation, property and business interruption insurance and
we may not be able to maintain insurance on acceptable terms, if at all. We currently carry no insurance specifically covering environmental
claims.

Our ability to use net operating loss carryforwards and certain other tax attributes to offset taxable income could be limited.

We plan to use our current year operating losses to offset taxable income from any revenue generated from operations, including BD
Arrangements.  To  the  extent  that  our  taxable  income  exceeds  any  current  year  operating  losses,  we  plan  to  use  our  net  operating  loss
carryforwards  to  offset  income  that  would  otherwise  be  taxable.  Our  federal  net  operating  loss  carryforwards  generated  in  tax  years
beginning before January 1, 2018 are only permitted to be carried forward for 20 years under applicable U.S. tax law. Under the 2017 Tax
Act, as modified by the Coronavirus Aid, Relief and Economic Security Act, or the CARES Act, our federal net operating losses generated in
tax years beginning after December 31, 2017 may be carried forward indefinitely, but the ability to deduct such federal net operating losses is
limited to 80% of taxable income. It is uncertain if and to what extent various states will conform to the 2017 Tax Act or the CARES Act.

In addition, under Sections 382 and 383 of the U.S. Internal Revenue Code of 1986, as amended, or the Code, and corresponding
provisions  of  state  law,  if  we  experience  an  “ownership  change,”  generally  defined  as  a  greater  than  50%  change,  by  value,  in  equity
ownership over a three-year period, our ability to use our net operating loss carryforwards and certain other tax attributes (such as R&D tax
credits) before the change to offset our income after the change may be limited. Due to our initial public offering and other shifts in our stock
ownership,  we  have  experienced  ownership  changes  in  the  past  and  may  experience  ownership  changes  in  the  future  as  a  result  of
subsequent  shifts  in  our  stock  ownership,  some  of  which  are  outside  our  control.  As  a  result,  our  use  of  federal  net  operating  loss
carryforwards and certain other tax attributes could be limited. State net operating loss carryforwards may be similarly limited. In addition, at
the state level, there may be periods during which the use of net operating losses is suspended or otherwise limited, which could accelerate
or permanently increase state taxes owed.

New tax laws or regulations, changes to existing tax laws or regulations or changes in their application to us or our customers may
have a material adverse effect on our business, cash flows, financial condition or results of operations.

New tax laws, statutes, rules, regulations, directives, decrees or ordinances could be enacted at any time. Further, existing tax laws,
statutes, rules, regulations, directives, decrees or ordinances could be interpreted, changed or modified. Any such enactment, interpretation,
change or modification could adversely affect us, possibly with retroactive effect. For example, the Inflation Reduction Act of 2022 imposes,
among  other  rules,  a  15%  minimum  tax  on  the  book  income  of  certain  large  corporations  and  a  1%  excise  tax  on  certain  corporate  stock
repurchases. In addition, for certain research and experimental expenses incurred in tax years beginning after December 31, 2021, the 2017
Tax  Act  requires  the  capitalization  and  amortization  of  such  expenses  over  five  years  if  incurred  in  the  United  States  and  fifteen  years  if
incurred outside the United States, rather than deducting such expenses currently. There have been legislative proposals to repeal or defer
the capitalization requirement, including legislation recently passed by the U.S. House of Representatives that would restore the deductibility
of  research  and  experimental  expenses  incurred  in  the  United  States  (but  not  research  and  experimental  expenses  incurred  outside  the
United  States);  however,  there  can  be  no  assurance  that  such  requirement  will  be  repealed,  deferred  or  otherwise  modified.  Changes  in
corporate tax rates, the realization of net deferred tax assets relating to our operations, the taxation of foreign earnings and the deductibility
of expenses under the 2017 Tax Act, as amended by the CARES Act or any future tax reform legislation, could have a material impact on the
value of our deferred tax assets, result in significant one-time charges and increase our future U.S. tax expense.

Future changes in financial accounting standards or practices may cause adverse and unexpected revenue fluctuations and
adversely affect our reported results of operations.

Future  changes  in  financial  accounting  standards  may  cause  adverse,  unexpected  revenue  fluctuations  and  affect  our  reported
financial  position  or  results  of  operations.  Financial  accounting  standards  in  the  United  States  are  constantly  under  review  and  new
pronouncements and varying interpretations of pronouncements have occurred frequently in the past and are expected to occur again in the
future. As a result, we may be required to

76

Table of Contents

make changes in our accounting policies. Those changes could affect our financial condition and results of operations or the way in which
such  financial  condition  and  results  of  operations  are  reported.  Compliance  with  new  accounting  standards  may  also  result  in  additional
expenses. As a result, we intend to invest all reasonably necessary resources to comply with evolving standards, and this investment may
result  in  increased  general  and  administrative  expenses  and  a  diversion  of  management  time  and  attention  from  business  activities  to
compliance activities.

We continue to incur increased costs as a result of operating as a public company, and our management devotes substantial time
to  new  compliance  initiatives.  In  addition,  we  are  obligated  to  develop  and  maintain  proper  and  effective  internal  control  over
financial  reporting.  In  the  future,  we  may  not  complete  our  analysis  of  our  internal  control  over  financial  reporting  in  a  timely
manner, or our internal control over financial reporting may not be determined to be effective, which may adversely affect investor
confidence in our company and, as a result, the value of our common stock.

As a public company, we incur significant legal, accounting, insurance and other expenses, and these expenses further increased in
connection  with  our  loss  of  “emerging  growth  company”  status  as  of  December  31,  2021.  As  a  public  company,  we  are  subject  to  the
reporting requirements of the Exchange Act, the Sarbanes-Oxley Act and the Dodd-Frank Act, as well as rules adopted, and to be adopted,
by  the  SEC  and  The  Nasdaq  Global  Select  Market.  Our  management  and  other  personnel  devote  a  substantial  amount  of  time  to  these
compliance initiatives. Moreover, these rules and regulations increase our legal and financial compliance costs and may make some activities
more  time-consuming  and  costly.  The  increased  costs  will  increase  our  net  loss.  For  example,  these  rules  and  regulations  make  it  more
difficult  and  more  expensive  for  us  to  obtain  director  and  officer  liability  insurance  and  we  may  be  required  to  incur  substantial  costs  to
maintain sufficient coverage. We cannot predict or estimate the amount or timing of additional costs we may incur in the future to respond to
these requirements. The impact of these requirements could also make it more difficult for us to attract and retain qualified persons to serve
on our board of directors, our board committees or as executive officers.

Specifically,  in  order  to  comply  with  the  requirements  of  being  a  public  company,  we  need  to  undertake  various  actions,  including
maintaining  effective  internal  controls  and  procedures.  The  Sarbanes-Oxley  Act  requires,  among  other  things,  that  we  maintain  effective
disclosure  controls  and  procedures  and  internal  control  over  financial  reporting.  We  are  continuing  to  develop  and  refine  our  disclosure
controls and other procedures that are designed to ensure that information required to be disclosed by us in the reports that we file with the
SEC is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that information
required  to  be  disclosed  in  reports  under  the  Exchange  Act  is  accumulated  and  communicated  to  our  principal  executive  and  financial
officers.  In  addition,  we  must  perform  system  and  process  evaluation  and  testing  of  our  internal  control  over  financial  reporting  to  allow
management to report on the effectiveness of our internal control over financial reporting, as required by Section 404(a) of the Sarbanes-
Oxley Act. Our compliance with Section 404(b) of the Sarbanes-Oxley Act requires that we incur substantial accounting expense and expend
significant management efforts. We currently do not have an internal audit staff and outsource this function to a third party. We have hired
and  will  need  to  retain  our  current  accounting  and  financial  staff  who  have  the  appropriate  public  company  experience  and  technical
accounting knowledge. As a result of our public float on June 30, 2023, commencing on December 31, 2023, we became a non-accelerated
filer. For so long as we remain a non-accelerated filer, our independent registered public accounting firm will not be required to attest to the
effectiveness of our internal control over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act. If we identify deficiencies
in our internal control over financial reporting that are deemed to be material weaknesses, investors may lose confidence in our operating
results and the price of our common stock could decline. In addition, if we are unable to continue to meet these requirements, we may not be
able to remain listed on The Nasdaq Global Select Market.

Our ability to successfully implement our business plan and comply with Section 404(a) of the Sarbanes-Oxley Act requires us to be
able to prepare timely and accurate financial statements. We expect that we will need to continue to improve existing, and implement new
operational  and  financial  systems,  procedures  and  controls  to  manage  our  business  effectively.  Any  delay  in  the  implementation  of,  or
disruption in the transition to, new or enhanced systems, procedures or controls may cause our operations to suffer, and we may be unable
to  conclude  that  our  internal  control  over  financial  reporting  is  effective.  This,  in  turn,  could  have  an  adverse  impact  on  the  price  for  our
common stock and could adversely affect our ability to access the capital markets.

Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.

We  designed  our  disclosure  controls  and  procedures  to  reasonably  assure  that  information  we  must  disclose  in  reports  we  file  or

submit under the Exchange Act is accumulated and communicated to management,

77

Table of Contents

and recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. We believe that any
disclosure  controls  and  procedures  or  internal  controls  and  procedures,  no  matter  how  well-conceived  and  operated,  can  provide  only
reasonable, not absolute, assurance that the objectives of the control system are met.

These inherent limitations include the realities that judgments in decision-making can be faulty and breakdowns can occur because
of  simple  error  or  mistake.  Additionally,  controls  can  be  circumvented  by  the  individual  acts  of  some  persons,  by  collusion  of  two  or  more
people or by an unauthorized override of the controls. Accordingly, because of the inherent limitations in our control system, misstatements
due to error or fraud may occur and not be detected.

If securities or industry analysts do not publish research, or publish inaccurate or unfavorable research, about our business, our
stock price and trading volume could decline.

Our stock price and trading volume is heavily influenced by the way analysts and investors interpret our clinical trial results, any BD
Arrangements we may enter into, our financial information and other disclosures. If securities or industry analysts do not publish research or
reports  about  our  business,  delay  publishing  reports  about  our  business  or  publish  negative  reports  about  our  business,  regardless  of
accuracy, our stock price and trading volume could decline.

Item 1C.    Cybersecurity.

Risk Management Strategy

We have implemented and maintain various information security processes. These processes are designed to identify, assess and
manage  material  risks  from  cybersecurity  threats  to  our  critical  computer  networks,  third-party  hosted  services,  communications  systems,
hardware and software, and our critical data, including intellectual property, strategic or competitive in nature, and proprietary or confidential
information, including clinical trial data, personal and financial information, referred to collectively as Information Systems and Data.

Our Chief Financial Officer, or CFO, together with our Incident Disclosure Committee, or IDC, Security Incident Response Team, or
SIRT, which is led by our head of information technology, or IT, and composed of two employees who have direct work experience in network
security, and third-party service providers, help identify, assess and manage the Company’s cybersecurity threats and risks. In doing so, they
identify and assess risks from cybersecurity threats by monitoring and evaluating our threat environment and the Company’s risk profile using
various methods including, for example, automated and manual tools, third-party threat assessments and intelligence feeds, subscribing to
reports  and  services  that  identify  cybersecurity  threats,  analyzing  reports  of  threats  and  threat  actors,  evaluating  the  Company’s  and  the
industry’s risk profile, evaluating reported threats, coordinating with law enforcement relating to threats, conducting threat assessments for
internal and external threats, conducting red/blue team testing and tabletop incident response exercises jointly with external third parties.

Depending  on  the  environment,  we  implement  and  maintain  various  technical,  physical  and  organizational  measures,  processes,
standards  and  policies  designed  to  manage  and  mitigate  material  risks  from  cybersecurity  threats  to  our  Information  Systems  and  Data,
including,  for  example:  an  incident  detection  and  response  plan  and  policy;  encryption  of  data;  network  security  controls;  access  controls;
physical security and employee training.

Our  assessment  and  management  of  material  risks  from  cybersecurity  threats  are  integrated  into  the  Company’s  overall  risk
management processes. For example, our IT department works with management to prioritize our risk management processes and mitigate
cybersecurity threats that are more likely to lead to a material impact to our business.

We use third-party service providers to assist us from time to time to identify, assess and manage material risks from cybersecurity
threats,  including  for  example  threat  intelligence  service  providers,  penetration  testing  firms,  dark  web  monitoring  services,  cybersecurity
consultants and software providers.

We use third-party service providers to perform a variety of functions throughout our business, such as application providers, hosting
companies, contract research organizations, and contract manufacturing organizations. We have a vendor management program to manage
cybersecurity risks associated with our use of these providers. The program includes a risk assessment for each vendor which includes a
security questionnaire, a review of the vendor’s written security program, and security assessment calls with the vendor's security team.

78

Table of Contents

Depending  on  the  nature  of  the  services  provided  the  sensitivity  of  the  Information  Systems  and  Data  at  issue,  and  the  identity  of  the
provider, our vendor management process may involve different levels of assessment designed to help identify cybersecurity risks associated
with a provider and impose contractual obligations related to cybersecurity on the provider.

For a description of the risks from cybersecurity threats that may materially affect the Company and how they may do so, see our risk
factors  under  Part  1.  Item  1A.  Risk  Factors  in  this  Annual  Report,  including  “We,  our  CROs,  our  CMOs,  our  current  and  potential  future
partners and other third parties we rely on or partner with could experience a cybersecurity incident that could harm our business”.

Governance

Our  board  of  directors,  or  the  Board,  addresses  the  Company’s  cybersecurity  risk  management  as  part  of  its  general  oversight
function.  The  Board  has  delegated  to  the  audit  committee  of  the  Board,  or  Audit  Committee,  responsibility  for  overseeing  the  Company’s
cybersecurity risk management processes generally, including oversight and mitigation of risks from cybersecurity threats.

Our  CFO  is  responsible  for  cybersecurity  risk  management  and  has  experience  overseeing  IT  departments  in  previous  roles.  Our
principal  accounting  officer,  or  PAO,  oversees  the  IT  department  and  in  that  capacity  is  responsible  for  hiring  appropriate  cybersecurity
personnel, helping to integrate cybersecurity risk considerations into the Company’s overall risk management strategy, and communicating
key priorities to relevant personnel. Our PAO has significant experience with managing access to key company-wide information systems.
Our head of IT is responsible for assessing and managing our material risks from cybersecurity threats and for our cybersecurity protections
generally, including helping prepare for cybersecurity incidents, approving cybersecurity processes and reviewing security assessments and
other security-related reports. Our head of IT has prior work experience in cybersecurity, holds relevant degrees and current cybersecurity
certifications. The Audit Committee receives periodic reports from our CFO and head of IT concerning cybersecurity threats and risks, and
the  processes  that  we  have  implemented  to  address  and  mitigate  them.  The  Audit  Committee  updates  the  Board  on  such  cybersecurity
issues  as  part  of  its  general  committee  report  to  the  Board  at  regular  Board  meetings.  Our  Board  is  responsible  for  approving  budgets  to
support those activities.

We  have  in  place  a  cybersecurity  incident  response  plan,  reviewed  by  the  Audit  Committee,  which  establishes  incident  response
processes,  policies  and  procedures.  Under  the  plan,  our  CFO,  as  incident  response  leader,  works  with  the  Company’s  SIRT  to  help  the
Company mitigate and remediate cybersecurity incidents of which they are notified.

Our IDC is notified and activated in the event of a significant cybersecurity incident. The IDC is composed of our CFO, the lead of the
SIRT, our General Counsel and other members of our legal and finance teams. In the event of a severe or major cybersecurity incident, the
IDC  will  oversee  and  coordinate  the  response,  determine  materiality  of  impact  and  any  disclosure  requirements  in  conjunction  with  legal
counsel and will ensure that the Audit Committee and/or the Board are updated and that required disclosures are made in a timely manner.

Item 2.    Properties.

We lease and occupy approximately 122,000 square feet of office and laboratory space in South San Francisco, California. In July
2022, we entered into an operating lease agreement, or the 2024 Lease Agreement, for our existing corporate office and laboratory space at
333 Oyster Point Boulevard, South San Francisco, California. The initial term of the 2024 Lease Agreement commenced on January 1, 2024

Item 7.    Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The  following  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  should  be  read  in  conjunction  with  our
audited  consolidated  financial  statements  and  related  notes  appearing  elsewhere  in  this  Annual  Report.  This  discussion  and  analysis
contains forward-looking statements based upon current beliefs, plans and expectations that involve risks, uncertainties and assumptions,
such  as  statements  regarding  our  plans,  objectives,  expectations,  intentions  and  projections.  Our  actual  results  and  the  timing  of  events
could  differ  materially  from  those  anticipated  in  these  forward-looking  statements  as  a  result  of  several  factors  that  could  impact  our
business, including those set forth in the section titled “Risk Factors” under Part I, Item 1A in this Annual Report on Form 10-K, or Annual
Report.  In  some  cases,  you  can  identify  forward-looking  statements  by  terminology  such  as  “anticipate,”  "aspire,"  “believe,”  “continue,”
“could,”  “estimate,”  “expect,”  “intend,”  “may,”  “plan,”  “potentially,”  “predict,”  “should,”  “will”  or  the  negative  of  these  terms  or  other  similar
expressions. See “Special Note Regarding Forward-Looking Statements” in this Annual Report.

In  addition,  statements  that  “we  believe”  and  similar  statements  reflect  our  beliefs  and  opinions  on  the  relevant  subject.  These
statements are based upon information available to us as of the date of this Annual Report, and while we believe such information forms a
reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate we
have conducted exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain
and investors are cautioned not to unduly rely upon these statements.

We  are  a  biopharmaceutical  company  focused  on  discovering  and  developing  novel,  potentially  life-changing  medicines  based  on
scientific  understanding  of  key  biological  pathways.  Our  mission  is  to  translate  complex,  powerful  biology  with  rigor  and  urgency  into  life-
changing  medicines.  Our  strategy  is  built  on  a  straightforward  central  premise:  create  an  environment  that  both  allows  drug  discovery
research to thrive by focusing on powerful human biology unconstrained by therapeutic area or technology approach and remain grounded in
the singular motivation of delivering impactful medicines to address critical unmet or underserved

Overview of Our Business

needs of patients suffering from grievous diseases. As explorers on the frontier of life-changing science, we aspire to operate one of the most
productive  research  and  development  engines  in  the  biopharmaceutical  industry.  All  therapeutic  candidates  in  our  pipeline  have  been
generated by our in-house discovery engine, led by biology and motivated by patient need.

Our biology-driven and therapeutic area agnostic discovery engine has produced a diverse pipeline of product candidates spanning
oncology,  liver  and  metabolic  disease  and  retinal  disease.  We  have  evolved  our  strategy  to  concentrate  our  resources  on  three  product
candidates  in  three  specific  disease  areas,  as  well  as  to  continue  our  discovery  research  efforts.  For  our  other  product  candidates  and
potential future opportunities that have been, and may in the future be, produced by our discovery engine, we are seeking collaboration, out
licensing, partnering or other business development arrangements, or BD Arrangements, with third-party partners with sufficient resources
and relevant domain expertise to further their development. We believe that this strategy, if successfully implemented, may enable more of
the programs in our pipeline to be advanced effectively and efficiently.

Pending Transactions Contemplated by the Merger Agreement

On  February  25,  2024,  we  entered  into  the  Merger  Agreement  with  Parent  and  Merger  Sub.  The  Merger  Agreement  provides  for,
among other things, (i) the acquisition of the Company by Parent through a cash tender offer, or the Offer, by Merger Sub for each issued
and  outstanding  share  of  our  common  stock  for  $1.55  per  share,  or  the  Offer  Price,  and  (ii)  the  merger  of  Merger  Sub  with  and  into  the
Company, or the Merger, with the Company surviving the Merger. Subject to the terms of the Merger Agreement, the Offer Price will be paid
subject to any applicable tax withholding and without interest.

We anticipate that the Offer and the Merger contemplated under the Merger Agreement will be consummated in the second quarter
of 2024. However, there can be no assurance that the Offer and the Merger contemplated by the Merger Agreement will be completed. If the
Merger is effected, our common stock will be delisted from The Nasdaq Global Select Market, our obligation to file periodic reports under the
Securities Exchange Act of 1934, as amended, or the Exchange Act, will terminate, and we will be privately held.

Pipeline Programs and Operational Updates

We are currently prioritizing the majority of our execution efforts and significant resources on three key development opportunities:

•

•

•

completing  a  Phase  1  Part  1b  dose  escalation  cohort  of  the  ongoing  Phase  1/2  trial  evaluating  NGM707  in  combination  with
KEYTRUDA® (pembrolizumab) for the treatment of patients with advanced or metastatic solid tumors;

designing a potential registrational trial of aldafermin in primary sclerosing cholangitis, or PSC, and continuing discussions with the
United  States  Food  and  Drug  Administration,  or  FDA,  including  on  the  proposed  utilization  of  a  primary  endpoint  composed  of
surrogate biomarkers with the goal of obtaining accelerated approval from the FDA; and

producing  a  toxicology  package  that  we  hope  will  support  the  potential  initiation  of  a  Phase  2  proof-of-concept  trial  of  NGM120  in
patients with hyperemesis gravidarum, or HG.

Subject to our ability to obtain sufficient additional capital, whether through financing activities or potential future BD Arrangements,
we may in the future pursue development of other product candidates and programs. While we may consider BD Arrangements to advance
these three key priorities for clinical development, we intend to invest our resources in their development, contingent upon capital availability
as described below, in the absence of BD Arrangements.

NGM707: ILT2/ILT4 Dual Antagonist Antibody for the Potential Treatment of Solid Tumors, Including MSS CRC Patients

NGM707, the lead asset in our myeloid reprogramming and checkpoint inhibition portfolio, is a dual antagonist monoclonal antibody
that  is  designed  to  improve  patient  immune  responses  to  tumors  by  inhibiting  both  Immunoglobulin-like  transcript  2,  or  ILT2,  and
Immunoglobulin-like transcript 4, or ILT4, receptors. We believe NGM707 has the potential to reprogram ILT4- and ILT2-expressing myeloid
cells to shift them from a suppressive state that restricts anti-tumor immunity to a stimulatory state that may promote anti-tumor immunity.
Blocking ILT2 also may reverse inhibition of ILT2-expressing lymphoid cells to further stimulate anti-tumor immune responses.

81

Table of Contents

• We  are  conducting  an  open-label  Phase  1/2  clinical  trial  evaluating  NGM707  as  a  monotherapy  and  in  combination  with

KEYTRUDA® (pembrolizumab) for the treatment of patients with advanced or metastatic solid tumors.

•

•

•

A  Phase  1  Part  1a  cohort  evaluating  NGM707  as  a  monotherapy  was  initiated  in  2021  and  a  Phase  1  Part  1b  cohort  evaluating
NGM707  in  combination  with  pembrolizumab  was  initiated  in  2022.  Two  Phase  2  expansion  cohorts  evaluating  NGM707  in
combination with pembrolizumab in specific tumor types were initiated in the first quarter of 2023. The Part 1a cohort has completed
enrollment. Enrollment in the Part 1b cohort is ongoing. We are no longer enrolling in the Phase 2 expansion cohorts.

In January 2024, we released data from the Phase 1b cohort. As of the data cutoff date of November 6, 2023, we had enrolled 46
heavily pretreated patients across multiple indications. The combination of NGM707 and pembrolizumab was found to be generally
well-tolerated  at  all  four  dose  levels  of  NGM707.  Of  37  response-evaluable  patients  (those  completing  at  least  one  on-treatment
scan),  there  were  four  confirmed  partial  responses,  including  one  pathological  complete  response  and  12  patients  with  stable
disease, representing an 11% overall response rate, or ORR, and a 43% disease control rate, or DCR. The pathological complete
response  patient  had  significant  target  lesion  reduction  that  allowed  subsequent  surgical  resection  of  all  gross  residual  disease,
resulting in a confirmed pathological complete response. Moreover, three of the four patients with confirmed partial responses had
active liver metastases at baseline that were fully or partially reduced. Of the eight response-evaluable patients with a diagnosis of
microsatellite  stable  colorectal  cancer,  or  MSS  CRC,  there  were  two  confirmed  partial  responses  (including  the  one  pathological
complete response) and two patients with stable disease, representing a 25% ORR and a 50% DCR. Immune checkpoint inhibitors,
alone and in combination with other therapies, have shown low or no benefit in MSS CRC patients. In addition, preliminary evidence
of myeloid reprogramming was seen in peripheral blood and in tumor biopsies consistent with the putative mechanism of NGM707.

Enrollment in the Phase 1b cohort is projected to be complete in the second quarter of 2024. We anticipate providing an update in
mid-2024  on  the  Phase  1  Part  1b  cohort  and  planned  next  steps  in  the  NGM707  program,  including  the  potential  for  additional
cohorts, which we expect will include MSS CRC patients. Clinical development of NGM707 beyond completing the Phase 1 Part 1b
cohort, including initiating additional cohorts, will require us to obtain the additional capital necessary to conduct such development.

Aldafermin: Engineered Analog of Human Hormone FGF19 for the Potential Treatment of PSC

Aldafermin is an engineered analog of human hormone fibroblast growth factor 19, or FGF19, that is administered through a once-
daily subcutaneous injection. PSC is a rare liver disease that irreparably damages the bile ducts, leading to bile acid dysregulation, which,
ultimately,  results  in  serious  liver  damage.  There  are  currently  no  FDA-  or  EU-  approved  therapies  for  PSC.  We  have  spent  more  than  a
decade discovering and developing product candidates that target various forms of cardio-metabolic and liver diseases, including PSC, and
our  product  candidates,  including  aldafermin,  stem  from  novel  insights  we  have  made  in  the  regulation  of  bile  acid  synthesis  and  liver
function.

Our decision to pursue the potential further clinical development of aldafermin as a treatment for PSC was informed by a large body
of  clinical  data.  Over  800  patients  across  multiple  indications  have  been  treated  with  aldafermin,  which  has  repeatedly  demonstrated
powerful bile acid suppression in patients with PSC and non-alcoholic steatohepatitis, or NASH. As a result, we believe aldafermin may have
the differentiated potential to directly address the underlying biology of PSC.

• We are continuing discussions with the FDA on the design of a potential registrational trial of aldafermin in PSC, including on the
proposed utilization of a primary endpoint composed of surrogate biomarkers with the goal of obtaining accelerated approval from
the FDA. We plan to continue working with the FDA to reach agreement on a trial design, with the goal of initiating trial enrollment by
the end of 2024, contingent upon reaching agreement with the FDA on trial design and obtaining the additional capital necessary to
conduct the potential registrational trial.

•

•

In January 2024, we announced that the FDA granted orphan drug designation for aldafermin for the treatment of PSC.

In November 2023, we presented positive Phase 2b results from the ALPINE 4 trial of aldafermin in compensated cirrhosis (F4) due
to NASH at AASLD The Liver Meeting.

NGM120: GFRAL Antagonist for the Potential Treatment of Hyperemesis Gravidarum

NGM120 is an antagonist antibody that binds to glial cell-derived neurotrophic factor receptor alpha-like, or GFRAL, and is designed
to block the effects of elevated serum levels of growth differentiation factor 15, or GDF15. We designed NGM120 as a potent, humanized
monoclonal  antibody  inhibitor  of  GFRAL.  Targeting  GFRAL  has  the  potential  to  ameliorate  the  metabolic  and  emetic  effects  caused  by
overstimulation of GFRAL neurons by excessive GDF15. HG is a severe condition that affects approximately 100,000 to 150,000 women in
the  United  States  each  year.  HG  is  characterized  by  intractable  nausea  and  vomiting  during  pregnancy,  resulting  in  dehydration,  debility,
weight loss and malnutrition. Genetic and serological studies have linked GDF15/GFRAL to HG. GDF15 levels have been shown to increase
steadily  in  the  first  12  weeks  of  pregnancy  and,  on  average,  are  higher  in  women  who  experience  nausea,  vomiting  or  HG  in  pregnancy.
There are currently no FDA-approved therapies for this condition.

• We are exploring the potential initiation of a Phase 2 proof-of-concept study of NGM120 for the treatment of HG by the end of 2024.
We are in the process of producing a toxicology package to submit to regulatory authorities in Australia or the United Kingdom that
we hope will support the potential initiation of that trial.

• We have previous clinical trial experience with NGM120, focused on a four-cohort Phase 1/2 clinical trial to assess NGM120’s effect
on cancer and cancer-related cachexia in patients with select advanced solid tumors, metastatic pancreatic cancer and metastatic
castration-resistant prostate cancer. NGM120 has been well tolerated in the trial, as well as in a Phase 1 study, together comprising
approximately  140  healthy  volunteers  and  cancer  patients  treated.  However,  a  clear  signal  of  response  to  NGM120  was  not
detected, and we do not plan to develop NGM120 further in oncology.

Additional Programs Currently Without Meaningful Resource Allocation

Due  to  the  need  to  conserve  capital  and  prioritize  focused  execution,  the  remainder  of  our  pipeline  includes  programs  (NGM438,
NGM831, NGM621 and NGM313) whose further development is dependent on our ability to secure potential future BD Arrangements, and,
in  the  absence  of  such  BD  Arrangements,  we  are  unlikely  to  advance  development  of  these  product  candidates  unless  our  portfolio
prioritization changes and we are able to secure the additional capital necessary to fund such development. As a result, we are seeking BD
Arrangements  with  third-party  partners  possessing  sufficient  resources  and  relevant  domain  expertise  in  the  relevant  therapeutic  area  in
order to further clinical development of these programs. These programs include:

• NGM438,  an  antagonist  antibody  that  is  designed  to  inhibit  leukocyte-associated  immunoglobulin-like  receptor  1,  or  LAIR1,  and
thereby  promote  anti-tumor  immune  responses,  and  NGM831,  an  antagonist  antibody  that  is  designed  to  block  the  interaction  of
Immunoglobulin-like  transcript  3,  or  ILT3,  receptor,  with  fibronectin,  as  well  as  other  cognate  ligands,  currently  being  studied  in  a
Phase 1/2 trial in combination with pembrolizumab. In 2022, we initiated an open-label, Phase 1/1b clinical trial to evaluate NGM438
as a monotherapy and in combination with pembrolizumab for the treatment of patients with advanced or metastatic solid tumors.
Both  the  Phase  1  Part  1a  cohort  evaluating  NGM438  as  a  monotherapy  and  the  Phase  1  Part  1b  cohort  evaluating  NGM438  in
combination  with  pembrolizumab  have  completed  enrollment.  In  2022,  we  also  initiated  an  open-label  Phase  1/1b  clinical  trial  to
evaluate  NGM831  as  a  monotherapy  and  in  combination  with  pembrolizumab  for  the  treatment  of  patients  with  advanced  or
metastatic  solid  tumors.  Both  the  Phase  1  Part  1a  cohort  evaluating  NGM831  as  a  monotherapy  and  the  Phase  1  Part  1b  cohort
evaluating  NGM831  in  combination  with  pembrolizumab  have  completed  enrollment.  In  2023,  we  initiated  an  open-label  Phase  1
Part 1c dose finding cohort of that trial evaluating the triplet combination of NGM831, NGM438 and pembrolizumab. This cohort is
anticipated to complete enrollment in the first half of 2024.

• NGM621,  a  humanized  Immunoglobulin  1,  or  IgG1,  monoclonal  antibody  administered  via  intravitreal,  or  IVT,  injection,  which  was
engineered  to  potently  bind  to,  and  be  a  long-acting  inhibitor  of,  complement  C3  with  the  treatment  goal  of  reducing  the  rate  of
disease progression in patients with geographic atrophy, or GA, secondary to age-related macular degeneration, or AMD. Our Phase
2 clinical trial which evaluated the efficacy and safety of NGM621 when given to patients with GA every four weeks or every eight
weeks via IVT injections compared to sham control did not meet its primary endpoint of a statistically significant reduction in the rate
of change in GA lesion area growth using slope analysis over 52 weeks of treatment with NGM621 versus sham.

• NGM313,  an  agonistic  antibody  that  selectively  activates  fibroblast  growth  factor  receptor  1c-beta-klotho,  or  FGFR1c/KLB,  which
regulates  insulin  sensitivity,  blood  glucose  and  liver  fat  and  is  administered  every  four  weeks  through  a  subcutaneous  injection.
Merck licensed NGM313 and other FGFR1c/KLB agonists in 2018, but terminated its license rights in 2023 and returned the program
to us.

Table of Contents

We have additional programs that are in various stages of development ranging from functional validation to preclinical development.
Given  the  breadth  of  opportunities  that  have  been,  and  may  in  the  future  be,  produced  by  our  discovery  engine,  we  are  also  seeking  BD
Arrangements with third-party partners to progress, in whole or in part, the development of one or more of our preclinical programs.

The  success  of  each  of  our  product  candidates  may  be  affected  by  numerous  factors,  including  preclinical  data,  clinical  data,
competition,  manufacturing  capability,  sales  capability,  any  future  BD  Arrangements,  the  sufficiency  of  our  cash  resources,  regulatory
matters, third-party payor matters and commercial viability. We do not have any products approved for sale and do not anticipate generating
revenue from product sales for the foreseeable future, if ever.

Operational Updates

We  do  not  own,  and  have  no  plans  to  establish,  any  manufacturing  facilities.  All  of  our  manufacturing  activities  are  outsourced  to
third-party  contract  development  and  manufacturing  organizations  or  third-party  contract  manufacturing  organizations,  which  we  refer  to
collectively as CMOs, which are generally single-source suppliers of the drug product or drug substance they are manufacturing for us. We
also  utilize  third-party  contract  research  organizations,  or  CROs,  to  carry  out  many  of  our  clinical  development  activities.  We  expect  to  be
reliant  on  CMOs  and  CROs  for  these  activities  for  the  foreseeable  future.  Significant  portions  of  our  R&D  resources  are  focused,  and  will
continue to be focused, on the manufacture and testing of clinical trial materials. If our CMOs and CROs fail to satisfy their contractual duties
to  us  or  meet  expected  deadlines  or  if  our  CMOs  experience  difficulties  in  scaling  production,  higher  than  anticipated  costs  or  lower  than
anticipated yields, product loss due to contamination, equipment failure, improper installation or operation of equipment, vendor or operator
error, turnover of qualified staff or improper storage conditions, difficulties with quality control, product stability or quality assurance testing, or
difficulties procuring raw materials or components, our ongoing and planned trials and possible acceleration or expansion of those trials may
be  delayed,  perhaps  substantially,  or  abandoned,  which  could  materially  and  adversely  affect  our  business.  For  example,  in  2022,  our
planned investigational new drug application, or IND, submissions for NGM438 and NGM831 were delayed due to challenges at one of our
CMOs with respect to the manufacture of those product candidates, primarily related to analytical method qualification and release testing. It
is possible that we could experience further supply-related delays that would create supply challenges and possible timing delays for ongoing
and  planned  clinical  trials  or  delay  the  commencement  of  first-in-human  testing  of  future  product  candidates.  In  addition,  there  have
historically been times of increased competition in the biotechnology industry for available CMO manufacturing slots and other capabilities
generally, which has had, and may in the future have, a negative impact on the availability of manufacturing capacity and therefore our ability
to supply clinical trial materials for planned, ongoing, accelerated or expanded clinical trials. Our CMOs’ facilities and operations have also
been adversely affected by labor, raw material and component shortages, high turnover of staff and difficulties in hiring trained and qualified
replacement staff. Changes in economic conditions, supply chain constraints, labor, raw material and component shortages and steps taken
by governments and central banks could lead to higher inflation than previously experienced or expected, which could, in turn, lead to an
increase in costs. These supply chain effects, increased competition and higher costs of acquired goods and services have not materially
impacted our results of operations for the year ended December 31, 2023, although they may negatively impact our business operations and
our financial results in the future.

In addition, some of our product candidates are currently manufactured solely at a facility in Lithuania. Following Russia's invasion of
Ukraine in February 2022, NATO deployed additional military forces to Eastern Europe, including to Lithuania. The ongoing conflict between
Russia and Ukraine and the retaliatory measures taken or that may be taken by the United States, NATO and others, including significant
sanctions  against  Russia,  create  global  security  concerns  and  regional  instability,  including  due  to  the  possibility  of  expanded  regional  or
global conflict, and are likely to have short-term and likely longer-term negative impacts on regional and global economies, any or all of which
could disrupt our supply chain and adversely affect our ability to conduct ongoing and future clinical trials of our product candidates and our
ability to raise capital on favorable terms.

In  July  2022,  we  entered  into  an  operating  lease  agreement,  or  the  2024  Lease  Agreement,  for  our  existing  corporate  office  and
laboratory  space  at  333  Oyster  Point  Blvd.,  South  San  Francisco,  California,  which  allows  us  to  remain  in  our  existing  facilities  through
December  31,  2033,  subject  to  our  compliance  with  the  2024  Lease  Agreement.  We  also  have  an  option  to  extend  the  2024  Lease
Agreement for a period of either eight or ten years after the initial ten-year term of January 1, 2024 to December 31, 2033. Base rent during
the initial ten-year term of the 2024 Lease Agreement will total $124.1 million.

We  seek  to  allocate  our  capital  efficiently  and  strategically  and  fund  our  development  portfolio  based  on  each  program’s  scientific

and other merits. Our discipline has been demonstrated by our decision not to proceed

84

Table of Contents

with development activities on multiple potentially viable product candidates for portfolio management and capital conservation reasons to
concentrate our resources and focus our execution on selected programs. Given that we will receive minimal funding from Merck in the first
half of 2024 and expect to receive no funding from Merck thereafter, we need to devote a substantial amount of our own financial resources
to fund our R&D programs, and we may need to delay or suspend development activities on product candidates that we consider promising
unless and until we are able to raise sufficient additional capital and/or we need to enter into additional BD Arrangements in order to proceed
with such development through to regulatory approval.

Restructuring

In  April  2023,  we  announced  a  restructuring  of  our  workforce  pursuant  to  which  our  workforce  was  reduced  by  74  people,  or
approximately 33% of our existing headcount as of such date. The restructuring, including cash payments, was substantially completed by
the end of the second quarter of 2023. We incurred approximately $4.9 million in restructuring charges in connection with the restructuring,
consisting of (i) approximately $4.2 million in cash-based expenses related to employee severance and notice period payments, benefits and
related  costs,  and  (ii)  approximately  $0.7  million  in  noncash  stock-based  compensation  expense  related  to  the  vesting  of  stock-based
awards.

Financial Highlights

Since inception, we have funded our operations primarily through:

•

•

•

•

•

fees  received  from  collaboration  partners,  which  since  inception  through  December  31,  2023  includes  reimbursement  of
R&D expenses of $544.6 million and upfront cash licensing fees of $123.0 million, primarily from Merck, and a payment of
$20.0 million from Merck to license NGM313 and related compounds;

proceeds  from  private  placements  of  convertible  preferred  stock  prior  to  our  initial  public  offering,  or  IPO,  including
approximately $106.0 million of our Series E convertible preferred stock purchased by Merck;

net  proceeds  from  our  IPO  in  2019  of  approximately  $107.8  million,  together  with  proceeds  from  the  concurrent  private
placement of shares of common stock to Merck of $65.9 million;

net proceeds of $134.6 million from the sale of approximately 5.3 million shares of our common stock in January 2021 upon
completion of an underwritten public offering of our common stock, or the follow-on offering, which included the full exercise
by the underwriters of their option to purchase additional shares; and

net  proceeds  of  $71.5  million  through  December  31,  2023  from  sales  of  approximately  4.1  million  shares  of  our  common
stock pursuant to at-the-market sales programs.

At December 31, 2023, we had $144.2 million in cash, cash equivalents and short-term marketable securities.

We  have  incurred  net  losses  each  year  since  our  inception.  As  of  December  31,  2023,  we  had  an  accumulated  deficit  of
$724.0 million. Our net losses have resulted from costs incurred in connection with our R&D programs and general and administrative, or
G&A, costs associated with our operations. Our net losses may fluctuate significantly from quarter-to-quarter and year-to-year, depending on
the  timing  of  our  clinical  trials  and  our  expenses  on  other  R&D  activities,  and  the  amount  of  R&D  funding  we  receive  from  future  BD
Arrangements,  if  any.  For  further  discussion  of  our  financial  position  and  future  sources  of  funding,  see  “Liquidity  and  Capital  Resources”
below.

Financial Operations Overview

Related Party Revenue

Our  revenue  to  date  has  been  generated  primarily  from  recognition  of  license  fees  and  R&D  service  funding  pursuant  to  our
collaboration  with  Merck.  Merck  is  also  a  significant  stockholder  and,  as  such,  collaboration  revenue  from  Merck  is  referred  to  as  related
party revenue.

Since  the  Company's  inception  through  December  31,  2023,  Merck  has  paid  us  $619.8  million  pursuant  to  the  terms  of  our
collaboration.  Due  to  the  nature  of  our  collaboration  with  Merck  and  the  timing  of  related  revenue  recognition,  our  revenue  has  fluctuated
from  period  to  period  in  the  past  and  has  decreased  significantly  in  2023  given  the  substantial  reduction  in  the  level  of  funding  we  have
received from Merck. In this regard, for the first half of

85

Table of Contents

2024,  we  expect  funding  and  related  party  revenue  from  Merck  to  be  minimal.  We  do  not  expect  the  research  program  term  of  the
collaboration  to  be  extended  and  accordingly  we  do  not  expect  any  funding  from  Merck  thereafter.  As  a  result,  we  believe  that  period-to-
period comparisons of our revenue may not be meaningful and should not be relied upon as being indicative of future performance.

We  use  the  cost-based  input  method  in  accordance  with  Accounting  Standards  Codification  606,  or  ASC  606,  to  calculate  the
corresponding amount of revenue to recognize at each reporting period. In applying the cost-based input measure of revenue recognition, we
measure actual costs incurred relative to budgeted costs to fulfill our performance obligation. We apply considerable judgment when we re-
evaluate the estimate of expected costs to satisfy the performance obligation each reporting period and make adjustments for any significant
changes. A significant change in the estimate of expected costs under the Amended Collaboration Agreement could have a material impact
on revenue recognized (including the possible reversal of previously recognized revenue) at each reporting period.

Research and Development Expenses

R&D efforts include drug discovery and other research activities and development activities relating to our product candidates, such
as manufacturing drug substance, drug product and other clinical trial materials, conducting preclinical studies and clinical trials and providing
support for these operations. Our R&D expenses consist of both internal and external costs. Our internal costs include employee, consultant,
facility and other R&D operating expenses. Our external costs include fees paid to CROs and other service providers in connection with our
clinical trials and preclinical studies, third-party license fees and CMO costs related to manufacturing drug substance, drug product and other
clinical trial materials.

Our R&D efforts are extensive and costly. Our R&D expenses related to the development of our product candidates consist primarily

of:

•

•

•

•

•

fees paid to our CROs in connection with our clinical trials and other related clinical trial fees, when applicable;

costs  related  to  acquiring  and  manufacturing  drug  substance,  drug  product  and  clinical  trial  materials,  and  the  costs  of  continued
testing, such as process validation testing and stability testing, of drug substance and drug product;

costs related to toxicology testing and preclinical studies;

salaries and related overhead expenses, which include stock-based compensation and benefits, for personnel in R&D functions;

fees paid to consultants for R&D activities;

• R&D operating expenses, including facility costs and depreciation expenses; and

•

costs related to compliance with regulatory requirements.

We need to devote a substantial amount of our own financial resources to our wholly-owned development programs, and we recently
have been focusing primarily on NGM707, aldafermin for the treatment of PSC and NGM120 for the treatment of HG. We will need to raise
significant  additional  capital  in  order  to  conduct  any  potential  registrational  trial  of  aldafermin  in  PSC.  In  addition,  clinical  development  of
NGM707  beyond  completing  the  Phase  1  Part  1b  cohort  evaluating  NGM707  in  combination  with  pembrolizumab,  including  initiating
additional cohorts, will require us to obtain the additional capital necessary to conduct such development. Moreover, further development of
NGM438, NGM831, NGM621, NGM313 and other product candidates and programs is dependent on our ability to secure potential future BD
Arrangements and, in the absence of such BD Arrangements, we are unlikely to be able to advance development of those programs unless
our portfolio prioritization changes and we are able to secure the additional capital necessary to fund such development. For the foreseeable
future, we anticipate a significant portion of our financial resources will be directed to activities required for our ongoing NGM707 trial and
efforts  to  initiate  clinical  trials  of  aldafermin  in  patients  with  PSC  and  NGM120  in  patients  with  HG.  We  expect  our  R&D  expenses  will
decrease  in  2024  compared  to  2023  as  we  suspend  development  activities  related  to  our  other  programs  and  due  to  a  decrease  in
compensation-related expenses following the workforce restructuring we implemented in the second quarter of 2023.

The successful development of our product candidates is highly uncertain. At this time, we cannot reasonably estimate the nature,
timing or costs of the efforts that will be necessary to complete the remainder of the development of our product candidates or if we will be
able to enter into BD Arrangements or otherwise raise adequate additional capital to meet our funding requirements to support such efforts.
This is due to the numerous risks and uncertainties associated with developing medicines, including the uncertainty of:

86

Table of Contents

•

•

•

the scope, rate of progress, results and expense of our ongoing, as well as any future, clinical trials and other R&D activities;

the impact and timing of any interactions with regulatory authorities, including timing and receipt of regulatory approvals;

our ability to hire and retain key R&D personnel;

• manufacturing scale-up challenges, production shortages or other supply disruptions for clinical trial materials;

•

•

•

the timely and quality performance of our CROs, CMOs and other service providers;

the effect of products that may compete with our product candidates or other market developments; and

our ability to expand and enforce our intellectual property portfolio.

A change in the development of a product candidate could cause a significant change in the costs, as well as the timing, associated
with  the  development  of  that  product  candidate.  For  example,  if  the  FDA  or  a  comparable  foreign  health  authority  were  to  require  us  to
conduct toxicology studies or clinical trials beyond those that we currently anticipate will be required for the initiation or completion of clinical
development of a product candidate, or if we experience significant delays in enrollment in any of our clinical trials, we could be required to
expend  significant  additional  financial  resources  and  time  on  the  completion  of  clinical  development.  For  additional  discussion  of  the  risks
and uncertainties associated with our R&D efforts, see “Risk Factors—Risks Related to Our Business and Industry,” “—Risks Related to Our
Dependence on Third Parties,” “—Risks Related to Regulatory Approvals” and "—Risks Related to Our Intellectual Property” in Part I, Item
1A of this Annual Report.

General and Administrative Expenses

G&A  expenses  consist  primarily  of  salaries  and  other  related  costs,  including  stock-based  compensation  and  benefits.  Other
significant costs include legal fees relating to patent and corporate matters, facility costs not otherwise included in R&D expenses and fees
for accounting and other consulting services.

We anticipate that our G&A expenses in 2024 will increase moderately compared to 2023. In 2024, our G&A expenses will include
an increase of approximately $10.2 million in operating lease expenses under the 2024 Lease Agreement which will be partially offset by a
decrease in compensation-related expenses due to the workforce restructuring we implemented in the second quarter of 2023. In addition,
we may continue to incur expenses associated with negotiating and entering into BD Arrangements. Further, we expect to incur legal and
other professional fees as a result of the potential consummation of the transactions contemplated under the Merger Agreement.

Revenue decreased $50.9 million and $22.5 million in the years ended December 31, 2023 and 2022, respectively, compared to the

prior year periods primarily due to a decrease in R&D revenue under our collaboration with Merck.

87

Table of Contents

Due to the nature of our collaboration with Merck, the timing of related revenue recognition and the substantial decrease in the level
of funding we received from Merck in 2023, our revenue has fluctuated from period to period in the past. In the first half of 2024, we expect
funding,  and  related  party  revenue,  from  Merck  to  be  minimal.  We  do  not  expect  the  research  program  term  of  the  collaboration  to  be
extended and accordingly we do not expect any funding from Merck thereafter.

_________________
(1) Internal and unallocated R&D expenses consist primarily of research supplies and consulting fees, which we deploy across multiple R&D programs and include restructuring
charges of $3.8 million in the year ended December 31, 2023.

R&D expenses decreased $63.0 million in the year ended December 31, 2023 compared to the same period in 2022 primarily due to
a decrease in expenses for our clinical trial of NGM621 of $21.7 million, a decrease in personnel expenses of $14.9 million, decreases in
expenses for our manufacturing activities and our clinical trials of aldafermin of $9.5 million, decreases in expenses for our clinical trials of
NGM707 and NGM120 of $7.5 million and $3.0 million, respectively, and a decrease in our internal and unallocated R&D expenses of $6.7
million which include restructuring charges of $3.8 million.

R&D expenses increased $19.4 million in the year ended December 31, 2022 compared to the same period in 2021 primarily due to
increases  in  external  expenses,  driven  by  our  ongoing  clinical  trials  of  NGM707,  NGM831,  NGM438  and  NGM120,  our  completed  trial  of
NGM621, and personnel expenses including an increase in stock-based compensation expense of $3.6 million, partially offset by a decrease
in expenses for our manufacturing activities and our clinical trials of aldafermin.

We expect our R&D expenses will decrease in 2024 compared to 2023 as we suspend development activities related to certain of
our  solid  tumor  oncology  and  other  programs  and  also  due  to  a  decrease  in  compensation-related  expenses  following  the  workforce
restructuring we implemented in the second quarter of 2023.

General and Administrative Expenses

G&A expenses decreased $2.7 million in the year ended December 31, 2023 compared to the same period in 2022 primarily due to a

decrease in compensation-related expenses of $3.2 million, partially offset by restructuring charges of $1.1 million.

G&A expenses increased $3.7 million in the year ended December 31, 2022 compared to the same period in 2021 primarily due to

an increase in compensation-related expenses of $3.3 million including an increase in stock-based compensation expense of $2.5 million.

We  anticipate  that  our  G&A  expenses  in  2024  will  increase  moderately  compared  to  2023  due  to  an  increase  in  operating  lease
expenses of approximately $10.2 million under the 2024 Lease Agreement, partially offset by a decrease in compensation-related expenses
due to the workforce restructuring we implemented in the

88

second  quarter  of  2023.  Further,  we  expect  to  incur  legal  and  other  professional  fees  as  a  result  of  the  potential  consummation  of  the
transactions contemplated under the Merger Agreement.

Interest Income, net  

Interest income, net increased $5.6 million and $3.3 million in the years ended December 31, 2023 and 2022, respectively, compared

to same prior year periods primarily due to higher interest rates.

Liquidity and Capital Resources

Funding Requirements

We have no products approved for commercial sale, have not generated any revenue from product sales to date and we are not and
may never be profitable. We have incurred losses in each year since commencing operations, and we expect to incur significant operating
losses in 2024 and over the next several years. As of December 31, 2023, we had an accumulated deficit of $724.0 million, and we expect
our accumulated deficit will continue to increase over time.

We  have  an  active  discovery  research  group  and  have  spent  significant  resources  to  fund  R&D  of  multiple  pipeline  programs.  In
2023, our execution efforts and resources were focused on our solid tumor oncology programs, NGM707, NGM438, NGM831 and NGM120.
In  2024,  we  are  narrowing  our  focus  to  advance  our  three  key  priorities  for  clinical  development  --  our  ongoing  NGM707  clinical  trial,  the
potential development of aldafermin for the treatment of PSC and the potential development of NGM120 for the treatment of HG -- as well as
to continue our discovery research efforts. We will need to raise significant additional capital in order to conduct any potential registrational
trial of aldafermin in PSC. In addition, clinical development of NGM707 beyond completing the Phase 1 Part 1b cohort evaluating NGM707 in
combination with pembrolizumab, including initiating additional cohorts, will require us to obtain the additional capital necessary to conduct
such development.

Due to the need to conserve capital and prioritize focused execution, the remainder of our pipeline includes programs whose further
development  is  dependent  on  our  ability  to  secure  potential  future  BD  Arrangements.  We  are  seeking  BD  Arrangements  with  third-party
partners with sufficient resources and relevant domain expertise in order to further the clinical development, if any, of NGM438, NGM831,
NGM621  and  NGM313.  Further  development  of  these  programs,  which  are  in  therapeutic  areas  where  clinical  development  is  relatively
resource intensive and can have long timelines to generate proof-of-concept data, is dependent on our ability to secure potential future BD
Arrangements. In the absence of such BD Arrangements for these programs, we are unlikely to be able to advance their development unless
our portfolio prioritization changes and we are able to secure the additional capital necessary to fund such development.

Prior to 2022, we received substantial R&D funding from our collaboration with Merck. However, beginning in April 2022 under the
narrower scope of the Amended Collaboration Agreement, R&D funding from Merck was substantially lower than the R&D funding previously
provided  by  Merck.  For  the  first  half  of  2024  we  expect  minimal  funding  from  Merck.  We  do  not  expect  the  research  program  term  of  the
collaboration to be extended and accordingly we do not expect any funding from Merck thereafter.

At  December  31,  2023,  we  had  $144.2  million  in  cash,  cash  equivalents  and  short-term  marketable  securities.  Our  cash
requirements  for  fiscal  year  2024  will  continue  to  be  driven  by  our  R&D  and  G&A  expenses.  In  2023  and  2022,  our  R&D  expenses  were
$118.0  million  and  $181.1  million,  respectively.  In  2024,  we  expect  our  R&D  expenses  to  decrease  compared  to  2023  as  we  limit  our
development activities to focus on the continued advancement of NGM707, as well as potential development activities related to aldafermin
for the treatment of PSC and NGM120 for the treatment of HG. In 2023 and 2022, our G&A expenses were $37.8 million and $40.5 million,
respectively. In 2024, we expect our G&A expenses will increase moderately compared to 2023 due to an increase in our operating lease
costs  of  $10.2  million  pursuant  to  the  2024  Lease  Agreement  we  entered  into  in  July  2022  for  our  current  corporate  office  and  laboratory
space in South San Francisco, California. Our previous lease expired on December 31, 2023. The 2024 Lease Agreement commenced on
January 1, 2024 and expires on December 31, 2033. In 2024, we are paying an initial monthly base rent of approximately $0.9 million, which
is subject to increases at an annual rate of 3.5% each year thereafter, plus certain operating and tax expenses. Further, we expect to incur
legal and other professional fees as a result of the potential consummation of the transactions contemplated under the Merger Agreement. In
addition, if the Merger is not consummated, we may face increased difficulties raising capital and may need to significantly delay, scale back
or  discontinue  development  of,  or  abandon  some  or  all  of,  our  product  candidates,  or  scale  back  or  discontinue  our  discovery  research
efforts.

Table of Contents

We believe that our existing cash, cash equivalents and short-term marketable securities will be sufficient to fund our operations for
at least one year from the date this Annual Report is filed. We have based these estimates on plans and assumptions that may prove to be
insufficient  or  inaccurate  (for  example,  with  respect  to  anticipated  costs,  timing  or  success  of  certain  activities),  and  we  could  utilize  our
available  capital  resources  sooner  than  we  currently  expect.  These  estimates  do  not  include  entering  into  BD  Arrangements  or  receiving
funds  through  debt  or  equity  financing  activities  and,  as  a  result,  unless  we  significantly  lower  our  use  of  cash,  we  may  no  longer  have
sufficient  cash,  cash  equivalents  and  short-term  marketable  securities  to  fund  our  operations  for  more  than  one  year  at  the  end  of  future
reporting  periods.  Our  forecast  of  the  time  period  through  which  our  financial  resources  will  be  adequate  to  support  our  operations  is  a
forward-looking statement that involves risks and uncertainties, and actual results could vary materially as a result of a number of factors,
including the factors discussed under “Risk Factors” in Part I, Item 1A of this Annual Report. Nonetheless, in order to advance our current
and potential future product candidates through development and to regulatory approval and commercialization, we need to raise significant
additional capital and we will need to enter into BD Arrangements for one or more of our wholly-owned programs. Neither may be possible
and,  as  a  result,  we  may  need  to  significantly  delay,  scale  back  or  discontinue  development  of  or  abandon  some  or  all  of  our  product
candidates, or scale back or discontinue our discovery research efforts, any of which could have a material adverse effect on our business,
operating results and prospects, or we may be required to cease operations altogether.

Sources of Liquidity

Cash and Investments

As of December 31, 2023, we had cash and cash equivalents of $55.8 million and short-term marketable securities of $88.4 million.

Merck Collaboration

The  revenue  we  received  under  our  collaboration  with  Merck  was  our  only  source  of  revenue.  In  the  first  half  of  2024,  we  expect
funding,  and  related  party  revenue,  from  Merck  to  be  minimal.  We  do  not  expect  the  research  program  term  of  the  collaboration  to  be
extended and accordingly we do not expect any funding from Merck thereafter.

Other Sources of Capital

In  June  2023,  we  entered  into  Amendment  No.  1,  or  the  Amendment,  to  the  Open  Market  Sales  Agreement

,  or  the  Sales
Agreement,  with  Jefferies  LLC,  or  Jefferies,  and  we  refer  to  the  Sales  Agreement  as  amended  as  the  Amended  Sales  Agreement.  As  of
December 31, 2023, up to $100.0 million of the Company's common stock remained available to be sold through or to Jefferies under the
Amended Sales Agreement, subject to conditions specified in the Amended Sales Agreement.

SM

We  plan  to  finance  our  future  cash  needs  through  public  or  private  equity  or  debt  offerings,  including  under  the  Amended  Sales
Agreement,  BD  Arrangements  or  a  combination  of  these  potential  financing  sources.  Additional  capital  may  not  be  available  in  sufficient
amounts, on reasonable terms or when we need it, if at all.

Our ability to raise additional capital through public or private equity or debt offerings may be adversely impacted by global economic
conditions  and  the  disruptions  to,  and  volatility  in,  the  credit  and  financial  markets  in  the  United  States  and  worldwide,  and  in  the
biotechnology  industry  specifically.  While  the  long-term  economic  impact  of  either  the  COVID-19  pandemic  or  ongoing  global  geopolitical
conflicts  is  difficult  to  assess  or  predict,  each  of  these  events  has  caused  significant  disruptions  to  the  global  financial  markets  and
contributed  to  a  general  global  economic  slowdown.  Furthermore,  higher  inflation  may  result  in  increased  operating  costs  (including  labor
costs)  and  may  affect  our  operating  budgets.  In  addition,  the  U.S.  Federal  Reserve  raised  interest  rates  in  2022  and  2023  in  response  to
concerns about inflation. Elevated interest rates, especially if coupled with reduced government spending and volatility in financial markets,
may  further  increase  economic  uncertainty.  Moreover,  the  closures  of  Silicon  Valley  Bank,  or  SVB,  and  other  banks  in  early  2023  have
resulted in broader financial institution liquidity risk and concerns. Although we incurred no losses as a result of the closure of SVB or other
banks,  future  adverse  developments  with  respect  to  specific  financial  institutions  or  the  broader  financial  services  industry  may  lead  to
liquidity shortages that could materially harm our business and financial condition. In this regard, we continue to maintain our cash at SVB
and other banks, often in balances that exceed the current FDIC insurance limits, and the failure of any bank in which we deposit our funds
could  reduce  the  amount  of  cash  we  have  available  for  our  operations  or  delay  our  ability  to  access  our  cash,  cash  equivalents  and
investments,  including  transferring  funds,  making  payments  or  receiving  funds.  We  also  may  not  be  able  to  access  additional  capital  on
favorable terms, or at all, which could materially and adversely affect our financial condition and our ability to pursue our business strategy.

Table of Contents

In  addition,  if  we  raise  additional  funds  by  issuing  equity  securities,  our  stockholders  may  experience  dilution.  Debt  financing,  if
available, may involve restrictive covenants. Any debt financing or additional equity that we raise may contain terms that are not favorable to
us  or  our  stockholders.  Furthermore,  any  securities  that  we  may  issue  may  have  rights  senior  to  those  of  our  common  stock  and  could
contain covenants or protective rights that would lead to restrictions on our operations and potentially impair our competitiveness, such as
limitations  on  our  ability  to  incur  additional  debt,  limitations  on  our  ability  to  acquire,  sell  or  license  intellectual  property  rights  and  other
operating restrictions that could adversely impact our ability to conduct our business.

While we may consider BD Arrangements to advance development of the product candidates that are our key priorities for clinical
development, we are seeking BD Arrangements with third-party partners to progress, in whole or in part, the development of one or more of
our other programs whose further development is dependent on our ability to secure potential future BD Arrangements or capital. We believe
that  this  strategy,  if  successfully  implemented,  may  enable  more  of  the  product  candidates  in  our  pipeline  to  be  advanced  effectively  and
efficiently.  However,  we  may  not  be  able  to  enter  such  BD  Arrangements  on  acceptable  terms,  if  at  all.  If  we  are  unable  to  secure  BD
Arrangements to support these programs, we are unlikely to be able to advance their development unless our portfolio prioritization changes
and  we  are  able  to  secure  additional  capital  necessary  to  fund  such  development.  We  may  discontinue  or  abandon  any  or  all  of  our
programs,  in  which  case  we  will  not  realize  any  return  on  our  investments  in  these  programs.  Even  if  we  are  successful  in  securing  BD
Arrangements for these or our other programs, we will likely have limited control over the amount and timing of resources that our partners
dedicate to the development or commercialization of the applicable product candidates. Our ability to generate revenue from any such BD
Arrangement will depend on the specific terms of the BD Arrangement.

If we are unable to raise adequate additional capital through public or private equity or debt offerings, BD Arrangements or otherwise,
on  acceptable  terms  or  at  all,  we  may  be  delayed  in  or  prevented  from  pursuing  our  planned  and  any  future  development  and
commercialization efforts, which will have a material adverse effect on our business, operating results and prospects, or we may be required
to cease operations altogether.

Cash used in operating activities in 2023 was $132.2 million, which consisted of a net loss of $142.4 million, adjusted for noncash
charges of $28.6 million and a change in operating assets and liabilities of $18.4 million. The noncash charges consisted primarily of stock-
based  compensation  expense  of  $28.7  million,  depreciation  expense  of  $2.2  million  and  noncash  lease  expense  of  $2.1  million,  partially
offset by an accretion of the discount on our marketable securities of $5.6 million. The change in operating assets and liabilities was mainly
driven by decreases in accrued liabilities of $17.0 million, a related party receivable of $7.5 million, operating lease liabilities of $5.4 million,
accounts payable of $5.0 million and prepaid expenses and other current assets of $1.6 million.

Cash used in operating activities in 2022 was $144.4 million, which consisted of a net loss of $162.7 million, adjusted for noncash

of  $6.1  million,  a  decrease  in  related  party  contract  assets  due  to  the  Amended  Collaboration  Agreement  with  Merck  of  $4.6  million,
amortization  of  a  premium  on  marketable  securities  of  $3.5  million  and  noncash  lease  expense  of  $1.8  million.  The  change  in  operating
assets  and  liabilities  was  mainly  driven  by  increases  in  contract  liabilities  of  $17.8  million,  related  party  receivable  of  $4.6  million,  prepaid

Investing Activities

Cash  provided  by  investing  activities  in  2023  was  $114.3  million,  which  consisted  primarily  of  $221.0  million  in  net  proceeds  on
maturity of marketable securities offset by purchases of marketable securities of $105.4 million. Cash provided by investing activities in 2022
was  $14.3  million,  which  consisted  primarily  of  $289.0  million  in  net  proceeds  on  maturity  of  marketable  securities  offset  by  purchases  of
marketable securities of $272.9 million. Cash used in investing activities in 2021 was $71.7 million, which consisted primarily of purchases of
marketable  securities  of  $293.5  million  primarily  from  the  net  proceeds  of  the  follow-on  offering,  partially  offset  by  $223.5  million  in  net
proceeds on maturity of marketable securities.

Financing Activities

Cash provided by financing activities in 2023 was $1.8 million, which consisted of net proceeds from our employee equity incentive
and  employee  purchase  plans.  Cash  provided  by  financing  activities  in  2022  was  $54.2  million,  which  consisted  of  net  proceeds  of  $49.4
million  from  the  sale  of  shares  of  our  common  stock  under  the  Sales  Agreement  and  proceeds  from  our  employee  equity  incentive  and
employee purchase plans of $4.8 million. Cash provided by financing activities in 2021 was $149.7 million, which consisted primarily of net
proceeds from the follow-on offering of $134.6 million and proceeds from employee equity incentive and employee purchase plans of $14.9
million.

Contractual Obligations

We  have  contractual  obligations  related  to  our  lease  liabilities.  In  July  2022,  we  entered  into  the  2024  Lease  Agreement  for  the
corporate  office  and  laboratory  space  in  South  San  Francisco,  California  that  we  occupied  pursuant  to  a  sublease  agreement  through
December  31,  2023.  The  initial  term  of  the  2024  Lease  Agreement  commenced  on  January  1,  2024  and  expires  on  December  31,  2033.
Base  rent  for  the  initial  ten-year  term  of  the  2024  Lease  Agreement  amounts  to  $124.1  million.  See  Note  6  to  our  consolidated  financial
statements included in Part II, Item 8, “Financial Statements and Supplementary Data,” of this Annual Report for additional information.

We  enter  into  agreements  in  the  normal  course  of  business  with  CROs  for  clinical  trials,  CMOs  and  other  vendors  for  preclinical
studies, supplies, manufacturing and other services and products for operating purposes. These agreements are generally cancellable at any
time  by  us,  upon  prior  written  notice,  and  may  include  cancellation  fees.  Given  that  the  amount  and  timing  related  to  such  payments  are
uncertain,  they  are  not  considered  to  be  contractual  obligations.  As  of  December  31,  2023,  we  did  not  accrue  for  any  termination  or
cancellation charges for any of these agreements as these were not considered probable. See "Liquidity and Capital Resources - Funding
Requirements" above for information regarding our expected R&D spend.

We are obligated to make future payments to third parties under in-license agreements, including sublicense fees, low single-digit
royalties and payments that become due and payable on the achievement of certain development and commercialization milestones. As the
amount  and  timing  of  sublicense  fees  and  the  achievement  and  timing  of  these  milestones  are  not  probable  and  estimable,  such
commitments  have  not  been  included  on  our  consolidated  balance  sheets  and  are  not  considered  to  be  contractual  obligations.  See
"Business—  Licensing  and  Collaboration  Arrangements"  in  Part  I,  Item  1  of  this  Annual  Report  for  additional  information  regarding  our
current in-license agreements.

Critical Accounting Policies and Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial
statements, which we have prepared in accordance with U.S. generally accepted accounting principles, or U.S. GAAP. The preparation of our
consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities
and the disclosure of contingent assets and liabilities at the date of our consolidated financial statements, as well as revenue and expenses
during the reported periods. We evaluate these estimates and judgments on an ongoing basis. In accordance with U.S. GAAP, we base our
estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which
form the basis for making judgments about the carrying value of

92

Table of Contents

assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates under different
assumptions or conditions.

While our significant accounting policies are described in Note 2 to our consolidated financial statements included in Part II, Item 8,
“Financial Statements and Supplementary Data,” of this Annual Report, we believe that the following critical accounting policies are the most
important policies in understanding and evaluating our financial condition and results of operations because they are complex and relate to
the more significant areas involving management’s judgment.

Accrued Research and Development Expenses

As  part  of  the  process  of  preparing  these  consolidated  financial  statements,  we  are  required  to  estimate  and  accrue  expenses,  the

largest of which are R&D expenses. This process involves:

•

•

•

•

•

•

•

identifying services that have been performed on our behalf by third-party vendors and estimating the level of service performed and
the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of actual cost;

estimating  and  accruing  expenses  in  our  consolidated  financial  statements  as  of  each  balance  sheet  date  based  on  facts  and
circumstances known to us at the time; and

periodically confirming the accuracy of our estimates with selected service providers and making adjustments, if necessary.

Examples of estimated R&D expenses that we accrue include:

fees paid to CROs and other service providers in connection with preclinical studies and clinical trials;

fees paid to investigative sites in connection with clinical trials;

fees  paid  to  CMOs  in  connection  with  the  production  of  clinical  trial  materials  and  to  procure  raw  materials  and  components  for
manufacture; and

professional service fees for consulting and other services.

We base our expense accruals related to clinical trials on our estimates of the services received and efforts expended pursuant to
contracts  with  multiple  research  institutions  and  CROs  that  conduct  and  manage  clinical  trials  on  our  behalf.  The  financial  terms  of  these
agreements  vary  from  contract  to  contract  and  may  result  in  uneven  payment  flows.  Payments  under  some  of  these  contracts  depend  on
factors such as the successful enrollment of patients and the completion of clinical study milestones. Our service providers generally invoice
us monthly in arrears for services performed. In accruing service fees, we estimate the period over which services will be performed and the
level of effort to be expended in each period. If we do not identify costs that we have begun to incur or if we underestimate or overestimate
the level of services performed or the costs of these services, our actual expenses could differ from our estimates.

Our  clinical  trials  have  been  executed  with  support  from  CROs  and  other  vendors.  We  accrue  costs  for  clinical  trial  activities
performed  by  CROs  based  upon  the  estimated  amount  of  work  completed  on  each  trial.  For  clinical  trial  expenses,  the  significant  factors
used  in  estimating  accruals  include  the  number  of  patients  enrolled,  the  activities  to  be  performed  for  each  patient,  the  number  of  active
clinical sites and the duration for which the patients will be enrolled in the trial. We monitor patient enrollment levels and related activities to
the extent possible through internal reviews, correspondence with CROs and review of contractual terms. We base our estimates on the best
information available at the time.

To date, we have not experienced significant changes in our estimates of accrued R&D expenses after a reporting period. However,
due  to  the  nature  of  estimates,  we  cannot  assure  that  we  will  not  make  changes  to  our  estimates  in  the  future  as  we  become  aware  of
additional information about the status or conduct of our clinical trials and other research activities.

Stock-Based Compensation

We account for stock-based compensation arrangements in accordance with Topic 718, Compensation—Stock Compensation.

Stock-based compensation expense represents the grant-date fair value of stock options and restricted stock units, or RSUs, granted
under our 2008 Equity Incentive Plan, or 2008 Plan, and our 2018 Amended and Restated Equity Incentive Plan, or 2018 Plan, and rights to
acquire stock granted under our 2019 Employee Stock Purchase Plan, or ESPP, recognized over the requisite service period of the awards
(usually the vesting period) on a straight-line basis, net of estimated forfeitures.

93

Table of Contents

We  use  the  Black-Scholes  option-pricing  model  to  calculate  the  grant-date  fair  value  of  stock  options.  The  Black-Scholes  option-
pricing  model  requires  the  use  of  subjective  assumptions,  including  stock  price  volatility,  the  expected  term  that  stock  options  will  remain
outstanding, risk-free interest rates and expected dividends.

The expected volatility is based on the historical volatility of our stock and the stock of similar entities within our industry over periods
commensurate  with  our  expected  term  assumption.  The  expected  term  of  stock  option  grants  represents  the  weighted-average  period  the
options are expected to remain outstanding and is based on the “simplified” method where the expected term is the midpoint between the
vesting  date  and  the  end  of  the  contractual  term  for  each  option.  We  base  the  risk-free  interest  rate  on  the  interest  rate  payable  on  U.S.
Treasury securities in effect at the time of grant for a period that is commensurate with the assumed expected option term. In reference to the
expected dividend yield assumption, we have not historically paid, and do not expect for the foreseeable future to pay, a dividend.

Smaller Reporting Company Status

We are a smaller reporting company as defined in the Exchange Act. We may take advantage of certain of the scaled disclosures
available to smaller reporting companies and will be able to take advantage of these scaled disclosures for so long as (i) our voting and non-

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of NGM Biopharmaceuticals, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of NGM Biopharmaceuticals, Inc. (the Company) as of December 31, 2023
and 2022, the related consolidated statements of operations, comprehensive loss, stockholders’ equity and cash flows for each of the three
years in the period ended December 31, 2023, and the related notes (collectively referred to as the “consolidated financial statements”). In
our  opinion,  the  consolidated  financial  statements  present  fairly,  in  all  material  respects,  the  financial  position  of  the  Company  at
December  31,  2023  and  2022,  and  the  results  of  its  operations  and  its  cash  flows  for  each  of  the  three  years  in  the  period  ended
December 31, 2023, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These  financial  statements  are  the  responsibility  of  the  Company's  management.  Our  responsibility  is  to  express  an  opinion  on  the
Company’s  financial  statements  based  on  our  audits.  We  are  a  public  accounting  firm  registered  with  the  Public  Company  Accounting
Oversight  Board  (United  States)  (PCAOB)  and  are  required  to  be  independent  with  respect  to  the  Company  in  accordance  with  the  U.S.
federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The
Company  is  not  required  to  have,  nor  were  we  engaged  to  perform,  an  audit  of  its  internal  control  over  financial  reporting.  As  part  of  our
audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion
on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or
fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the
amounts  and  disclosures  in  the  financial  statements.  Our  audits  also  included  evaluating  the  accounting  principles  used  and  significant
estimates  made  by  management,  as  well  as  evaluating  the  overall  presentation  of  the  financial  statements.  We  believe  that  our  audits
provide a reasonable basis for our opinion.

Critical Audit Matters

Critical audit matters are matters arising from the current period audit of the financial statements that were communicated or required to be
communicated  to  the  audit  committee  and  that:  (1)  relate  to  accounts  or  disclosures  that  are  material  to  the  financial  statements  and  (2)
involved our especially challenging, subjective or complex judgments. We determined that there are no critical audit matters.

/s/ Ernst & Young LLP

We have served as the Company’s auditor since 2008.

1. Organization and Description of Business

NGM BIOPHARMACEUTICALS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NGM  Biopharmaceuticals,  Inc.  and  its  wholly-owned  subsidiary,  NGM  Biopharmaceuticals  Australia  Pty  Ltd.,  or  NGM  Australia,
collectively  referred  to  as  the  Company,  is  a  biopharmaceutical  company  focused  on  discovering  and  developing  novel,  potentially  life-
changing  medicines  based  on  scientific  understanding  of  key  biological  pathways  underlying  grievous  diseases  with  critical  unmet  or
underserved patient need. The Company's portfolio of product candidates ranges from early discovery to Phase 2b development.

The Company was incorporated in Delaware in December 2007 and commenced operations in 2008. The Company's headquarters

are located at 333 Oyster Point Blvd., South San Francisco, California 94080.

Pending Transactions Contemplated by the Merger Agreement

On February 25, 2024, the Company entered into the Agreement and Plan of Merger, dated as of February 25, 2024, or the Merger
Agreement, with Atlas Neon Parent, Inc., a Delaware corporation, or Parent, and Atlas Neon Merger Sub, Inc., a Delaware corporation and a
wholly-owned subsidiary of Parent, or Merger Sub. Parent and Merger Sub are affiliates of The Column Group, LP, which, along with certain
of its affiliates, is collectively referred to as TCG. TCG is the Company's largest stockholder, holding approximately 26.7% of the Company's
common stock as of December 28, 2023.

The Merger Agreement provides for, among other things, (i) the acquisition of the Company by Parent through a cash tender offer, or
the Offer, by Merger Sub for each issued and outstanding share of the Company’s common stock for $1.55 per share, or the Offer Price, and
(ii) the merger of Merger Sub with and into the Company, or the Merger, with the Company surviving the Merger. Subject to the terms of the
Merger Agreement, the Offer Price will be paid subject to any applicable tax withholding and without interest.

Upon the unanimous recommendation of the special committee of the Company's board of directors, or the Special Committee, the
members  of  the  Company's  board  (other  than  David  V.  Goeddel,  Ph.D.  and  Roger  M.  Perlmutter,  M.D.,  Ph.D.  who  recused  themselves
because of their relationship to TCG, and William J. Rieflin, who recused himself because he had entered into the Rollover Agreement (as
defined  in  the  Merger  Agreement)  at  the  time  of  the  board's  determination)  have  unanimously  determined  that  the  terms  of  the  Offer,  the
Merger  and  the  other  transactions  contemplated  by  the  Merger  Agreement  are  fair  to  and  in  the  best  interests  of  the  Company  and  the
Unaffiliated  Stockholders  (as  defined  in  the  Merger  Agreement),  authorized  and  approved  the  execution,  delivery  and  performance  by  the
Company of the Merger Agreement and, subject to the terms and conditions of the Merger Agreement, the consummation by the Company of
the transactions contemplated by the Merger Agreement, declared the Merger Agreement and the transactions contemplated by the Merger
Agreement  advisable  and  recommended  that  the  Unaffiliated  Stockholders  accept  the  Offer  and  tender  their  shares  of  common  stock
pursuant to the Offer.

The Offer is being made subject to all terms and conditions set forth in the Offer to Purchase, dated March 8, 2024, or, as it may be
amended  or  supplemented  from  time  to  time,  the  Offer  to  Purchase,  and  in  the  related  Letter  of  Transmittal,  or  as  it  may  be  amended  or
supplemented from time to time, the Letter of Transmittal. The Offer to Purchase and the Letter of Transmittal constitute the Offer. The Offer
will expire at one minute after 11:59 p.m., Eastern time, on April 4, 2024, unless extended in accordance with the terms of the Offer and the
Merger Agreement and the applicable rules and regulations of the U.S. Securities and Exchange Commission, or the SEC.

Pursuant to the terms of the Merger Agreement, as of the effective time of the Merger, or the Effective Time, by virtue of the Merger
and  without  any  action  on  the  part  of  the  holders,  (i)  each  outstanding  share  of  the  Company's  common  stock  (other  than  any  shares  of
common stock (a) held in the treasury of the Company, (b) owned, directly or indirectly by TCG, Parent, Merger Sub or any other subsidiary
of Parent, or the Rollover Stockholders (as defined in the Merger Agreement) at the commencement of the Offer, (c) irrevocably accepted for
purchase in the Offer or (d) owned by any stockholders who are entitled to and who properly exercise appraisal rights under Delaware law)
will be converted into the right to receive the Offer Price without interest, less any applicable tax withholding; (ii) the vesting of each option to
purchase shares of the Company's common stock, or the Company Stock Options, shall be accelerated and (A) each Company Stock Option
that has an exercise price per share that is less than the Offer Price, or an In-the-Money Option, that is then outstanding will be cancelled
and,  in  exchange  therefor,  the  holder  of  such  cancelled  In-the-Money  Option  will  be  entitled  to  receive  an  amount  in  cash,  without  any
interest thereon and subject to applicable tax withholding, equal to the product of (x) the total number of shares of the Company's common
stock underlying such In-the-Money Option as of immediately prior to

102

Table of Contents

the Effective Time multiplied by (y) the excess of the Offer Price over the applicable exercise price per share of the common stock underlying
such In-the-Money Option, and (B) each Company Stock Option that is not an In-the-Money Option will be cancelled for no consideration;
and (iii) each unvested restricted stock unit, or RSU, of the Company that is then outstanding shall become immediately vested in full and
cancelled, and, in exchange therefor, the holder of such cancelled RSU will be entitled to receive an amount in cash without interest, less any
applicable tax withholding, equal to the Offer Price.

Merger Sub’s obligation to accept shares of the Company's common stock tendered in the Offer is subject to conditions, including: (i)
that the number of shares of the Company's common stock validly tendered and not validly withdrawn, equals at least a majority of all shares
of  the  Company's  common  stock  then  owned  by  the  Unaffiliated  Stockholders  as  of  the  expiration  of  the  Offer;  (ii)  the  accuracy  of  the
Company’s representations and warranties contained in the Merger Agreement (subject to certain exceptions and qualifications described in
the Merger Agreement and except, generally, for any inaccuracies that have not had a Company Material Adverse Effect (as defined in the
Merger Agreement)); (iii) the Company’s performance in all material respects of its obligations under the Merger Agreement and (iv) the other
conditions  set  forth  in  Exhibit  A  to  the  Merger  Agreement.  The  obligations  of  Parent  and  Merger  Sub  to  consummate  the  Offer  and  the
Merger under the Merger Agreement are not subject to a financing condition.

Following  the  completion  of  the  Offer,  subject  to  the  absence  of  injunctions  or  other  legal  restraints  preventing  or  prohibiting  the
consummation of the Merger, Merger Sub will merge with and into the Company, with the Company surviving as a wholly-owned subsidiary
of  Parent,  pursuant  to  the  procedure  provided  for  under  Section  251(h)  of  the  Delaware  General  Corporation  Law,  without  any  additional
stockholder approvals. The Merger will be effected as soon as practicable following the time at which Merger Sub purchases the shares of
the Company's common stock validly tendered and not withdrawn in the Offer.

The Merger Agreement contains customary representations and warranties by Parent, Merger Sub and the Company. The Merger
Agreement also contains customary covenants and agreements, including with respect to the operations of the Company's business between
signing and closing.

The Merger Agreement contains customary non-solicitation restrictions prohibiting the Company’s solicitation of alternative business
combination  transactions  and  restricts  the  Company’s  ability  to  furnish  non-public  information  to,  or  participate  in  any  discussions  or
negotiations with, any third party with respect to any such alternative business combination transaction, subject to customary exceptions in
the event of an acquisition proposal that was not solicited in violation of these restrictions and that our board of directors (acting upon the
recommendation of the Special Committee) or the Special Committee determines constitutes or could reasonably be expected to lead to a
Superior Company Proposal (as defined in the Merger Agreement).

The Merger Agreement contains customary termination rights for both Parent and Merger Sub, on the one hand, and the Company,
on  the  other  hand,  including,  among  others,  for  failure  to  consummate  the  Offer  on  or  before  June  15,  2024.  If  the  Merger  Agreement  is
terminated under certain circumstances specified in the Merger Agreement in connection with the Company’s entry into an agreement with
respect to a Superior Company Proposal, the Company will be required to pay Parent a termination fee of $2.0 million.

We anticipate that the Offer and the Merger contemplated under the Merger Agreement will be consummated in the second quarter
of 2024. However, there can be no assurance that the Offer and the Merger contemplated by the Merger Agreement will be completed. If the
Merger is effected, the Company’s common stock will be delisted from The Nasdaq Stock Market LLC and the Company’s obligation to file
periodic reports under the Securities Exchange Act of 1934, as amended, or the Exchange Act, will terminate, and NGM Bio will be privately
held.

Pending  consummation  of  the  Offer  and  the  Merger,  the  Merger  Agreement  generally  requires  the  Company  to  operate  in  the
ordinary  course  of  business  consistent  with  past  practice  and  restricts  the  Company  from  taking  certain  actions  with  respect  to  the
Company's business and financial affairs without Parent’s consent. Such restrictions will be in place until either the Offer and the Merger are
consummated  or  the  Merger  Agreement  is  terminated.  These  restrictions  could  restrict  the  Company's  ability  to  pursue  or  prevent  the
Company  from  pursuing  attractive  business  or  fundraising  opportunities  (if  any)  that  arise  prior  to  the  consummation  of  the  Offer  and  the
Merger.  For  example,  the  Company's  ability  to  raise  additional  capital  through  the  issuance  of  equity  securities,  incur  indebtedness  or  to
pursue business development or similar arrangements are generally restricted without Parent’s consent during the pendency of the Offer and
the Merger.

2. Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or U.S.
GAAP, and include the consolidated accounts of NGM Biopharmaceuticals, Inc. and its wholly-owned foreign subsidiary, NGM Australia. All
intercompany balances and transactions have been eliminated upon consolidation.

Use of Estimates

The  preparation  of  consolidated  financial  statements  in  conformity  with  U.S.  GAAP  requires  management  to  make  judgments,
assumptions  and  estimates  that  affect  the  reported  amounts  of  assets,  liabilities,  revenues  and  expenses.  Specific  accounts  that  require
management  estimates  include,  but  are  not  limited  to,  stock-based  compensation  expense,  clinical  trial  accruals,  other  accruals  including
contract manufacturing accruals and revenue recognition in accordance with Accounting Standards Update, or ASU, 2014-09, Revenue from
Contracts  with  Customers  (Topic  606),  or  ASC  606.  Management  bases  its  estimates  on  historical  experience  and  on  various  other
assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the
carrying  value  of  assets  and  liabilities  that  are  not  readily  apparent  from  other  sources.  Actual  results  could  differ  materially  from  those
estimates, and to the extent that there are differences between management's estimates and actual results, the Company's future financial
statement presentation, financial condition, results of operations and cash flows may be affected.

Sources and Uses of Liquidity

Since  inception,  the  Company  has  incurred  net  losses  and  negative  cash  flow  from  operations.  During  the  years  ended
December 31, 2023, 2022 and 2021, the Company incurred net losses of $142.4 million, $162.7 million and $120.3 million, respectively. As
of  December  31,  2023,  the  Company  had  an  accumulated  deficit  of  $724.0  million.  The  Company  expects  its  accumulated  deficit  will
continue to increase over time and does not expect to experience positive cash flows from operations in the near future.

As of December 31, 2023, the Company had $144.2 million of cash, cash equivalents and short-term marketable securities.

In  June  2020,  the  Company  entered  into  an  Open  Market  Sale  Agreement

,  or  the  Sales  Agreement,  with  Jefferies  LLC,  or
Jefferies, pursuant to which the Company could sell, from time to time, through or to Jefferies, up to an aggregate of $150.0 million of the
Company’s common stock. In June 2023, the Company entered into Amendment No. 1, or the Amendment, to the Sales Agreement, and the
Sales Agreement as amended is referred to as the Amended Sales Agreement. In connection with the Amendment, the Company filed a new
shelf registration statement on Form S-3 which the SEC declared effective in August 2023. The Amended Sales Agreement provides for the
issuance  and  sales  of  shares  of  the  Company's  common  stock  having  an  aggregate  offering  price  of  up  to  $100.0  million  through  or  to
Jefferies. As of December 31, 2023, up to $100.0 million of the Company's common stock remained available to be sold under the Amended
Sales Agreement, subject to conditions specified in the Amended Sales Agreement.

SM

The  Company  believes  its  existing  cash,  cash  equivalents  and  short-term  marketable  securities  will  be  sufficient  to  fund  its

operations for a period of at least one year from the issuance of these consolidated financial statements.

To fully implement the Company’s business plan and fund its operations, the Company needs to raise significant additional capital
through  public  or  private  equity  or  debt  offerings  (which  may  include  potential  net  proceeds  from  future  sales  of  the  Company's  common
stock, if any, under the Amended Sales Agreement), potential future collaboration, out licensing, partnering or other business development
arrangements, or BD Arrangements, or a combination of the foregoing. None may be possible and, as a result, the Company may need to
significantly delay, scale back or discontinue development of or abandon some or all of its product candidates, or scale back or discontinue
the Company's discovery research efforts, any of which could have a material adverse effect on the Company's business, operating results
and prospects, or the Company may be required to cease operations altogether.

Fair Value of Financial Instruments

The  carrying  amounts  of  cash  and  cash  equivalents,  the  related  party  receivable  from  collaboration  and  other  current  assets  and

liabilities approximate their respective fair values due to their short-term nature.

Cash and Cash Equivalents

Cash and cash equivalents are stated at fair value. Cash equivalents are securities with an original maturity of three months or less
at  the  time  of  purchase.  The  Company  limits  its  credit  risk  associated  with  cash  and  cash  equivalents  by  investing  in  highly  rated  money
market  funds  and  placing  its  cash  with  banks  it  believes  are  highly  creditworthy  in  amounts  that  may  at  times  exceed  Federal  Deposit
Insurance  Corporation,  or  FDIC,  limits.  As  of  December  31,  2023  and  2022,  cash  and  cash  equivalents  consisted  of  bank  deposits  and
investments in money market funds. The Company’s bank deposits as of December 31, 2023 and 2022 included certain amounts over the
FDIC limits.

Marketable Securities

The appropriate classification of the Company’s marketable securities is determined at the time of purchase and such designations
are  re-evaluated  at  each  balance  sheet  date.  The  Company’s  securities  are  considered  as  available-for-sale  and  carried  at  estimated  fair
values and reported in cash equivalents and short-term marketable securities. Unrealized gains and losses on available-for-sale securities
are  excluded  from  net  loss  and  reported  in  accumulated  other  comprehensive  income  (loss)  as  a  separate  component  of  stockholders’
equity. Interest income, net, includes interest, amortization of purchase premiums and accretion of purchase discounts, realized gains and
losses on sales of securities and other-than-temporary declines in the fair value of securities, if any. The cost of securities sold is based on
the specific identification method.

The Company’s investments are regularly reviewed for any impairments in fair value. This review includes the consideration of the
cause of the impairment, including the creditworthiness of the security issuers, the number of securities in an unrealized loss position, the
severity and duration of the unrealized losses, whether the Company has the intent to sell the securities and whether it is more likely than not
that the Company will be required to sell the securities before the recovery of their amortized cost basis. When the Company determines that
the  investment  is  impaired,  the  Company  reduces  the  carrying  value  of  the  security  it  holds  and  records  a  loss  for  the  amount  of  such
decline. As of December 31, 2023, the Company did not record any impairments related to its securities.

Restricted Cash

The Company’s restricted cash balances represent collateral required under the Company’s facility lease agreements. Collateral that
will  not  be  returned  to  the  Company  within  twelve  months  from  the  date  of  these  consolidated  financial  statements  is  classified  as  a  non-
current asset.

Concentration of Credit and Other Risks

Cash,  cash  equivalents  and  marketable  securities  from  the  Company’s  available-for-sale  and  marketable  securities  portfolio
potentially subject the Company to concentrations of credit risk. The Company is invested in money market funds and marketable securities
through custodial relationships with major United States, or U.S., banks. Under its investment policy, the Company limits amounts invested in
such securities by credit rating, maturity, industry group, investment type and issuer, except for securities issued by the U.S. government.

Related party receivables from collaboration and partnering arrangements are typically unsecured. Accordingly, the Company may
be  exposed  to  credit  risk  generally  associated  with  its  current  amended  and  restated  research  collaboration,  product  development  and
license agreement, or the Amended Collaboration Agreement, with Merck Sharp & Dohme, LLC, or Merck, and any future collaboration or
partnering  arrangements  with  other  potential  future  partners.  To  date,  the  Company  has  not  experienced  any  losses  related  to  these
receivables.

Amounts recognized as revenue prior to the Company having an unconditional right (other than a right that is conditioned only on the
passage of time) to receipt are recorded as contract assets in the Company's consolidated balance sheets. Although the Company expects
to  have  an  unconditional  right  to  receive  such  amounts,  the  Company  may  be  exposed  to  the  risk  of  not  receiving  the  recorded  amounts
under  its  current  collaboration  agreement  with  Merck  and  any  future  collaboration  or  partnering  arrangements  with  other  potential  future
partners. To date, the Company has not experienced any losses related to contract assets.

The Company's related party revenue from Merck accounted for 100% of the Company’s revenue for the years ended December 31,

2023, 2022 and 2021.

105

Table of Contents

Property and Equipment, Net

Property  and  equipment  are  recorded  at  cost  and  consist  of  computer  equipment,  laboratory  equipment  and  office  furniture  and
leasehold  improvements.  Maintenance  and  repairs,  and  training  on  the  use  of  equipment,  are  expensed  as  incurred.  Costs  that  improve
assets or extend their economic lives are capitalized. Depreciation is recognized using the straight-line method based on an estimated useful
life of the asset, which is as follows:

Computer equipment
Laboratory equipment and office furniture
Leasehold improvement

Leases

3 years
3 years
Shorter of life of asset or lease term

The  Company  determines  if  an  arrangement  is  a  lease  at  inception.  Lease  assets  represent  the  Company's  right  to  use  an
underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease.
Lease liabilities are measured at the lease commencement date as the present value of future minimum lease payments over the term of the
lease.  Lease  assets  are  measured  as  the  lease  liability  plus  initial  direct  costs  and  prepaid  lease  payments  less  lease  incentives.  In
measuring the present value of the future minimum lease payments, the Company generally uses its incremental borrowing rate. The lease
term  is  the  noncancelable  period  of  the  lease  and  includes  options  to  extend  or  terminate  the  lease  when  it  is  reasonably  certain  that  an
option  will  be  exercised.  Leases  with  terms  of  12  months  or  less  are  not  recorded  on  the  Company's  balance  sheet.  Lease  expense  is
recognized on a straight-line basis over the lease term, or in some cases, the useful life of the underlying asset. The Company accounts for
the lease and non-lease components as a single lease component. The Company’s lease agreement for its corporate office and laboratory
space is classified as an operating lease.

Impairment of Long-Lived Assets

Long-lived  assets,  such  as  property  and  equipment,  are  reviewed  for  impairment  whenever  events  or  changes  in  circumstances
indicate  that  the  carrying  amount  of  an  asset  may  not  be  recoverable.  Recoverability  of  assets  to  be  held  and  used  is  measured  by  a
comparison of the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the
carrying amount of an asset exceeds its estimated undiscounted future cash flows, an impairment charge is recognized as the amount by
which the carrying amount of the asset exceeds the estimated fair value of the asset. As of December 31, 2023 and 2022, no revision to the
remaining useful lives or write-down of long-lived assets was required.

Income Taxes

Income  taxes  are  accounted  for  under  the  liability  method.  Deferred  tax  assets  and  liabilities  are  recognized  for  the  future  tax
consequences  attributable  to  the  differences  between  the  financial  statement  carrying  amounts  of  existing  assets  and  liabilities  and  their
respective tax bases and the operating loss and tax credit carryforwards. Valuation allowances are established when necessary to reduce
deferred tax assets to the amount expected to be realized. Deferred tax assets and liabilities are measured at the balance sheet date using
the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or
settled.  The  effect  on  deferred  tax  assets  and  liabilities  of  a  change  in  tax  rates  is  recognized  in  the  period  such  tax  rate  changes  are
enacted. The net deferred tax assets have been fully offset by a valuation allowance.

Revenue Recognition

Under  ASC  606,  the  Company  estimates  each  arrangement’s  total  transaction  price,  which  includes  unconstrained  variable
consideration, and the recognition of that transaction price based on a cost-based input method that requires estimates to determine, at each
reporting period, the percentage of completion based on the estimated total effort required to complete the project and the total transaction
price. The unconstrained variable consideration amount included in the transaction price represents an amount for which it is probable that a
significant reversal of cumulative revenue recognized will not occur.

The  Company  applies  the  following  five-step  revenue  recognition  model  outlined  in  ASC  606  to  adhere  to  this  core  principle:  (1)
identify  the  contract(s)  with  a  customer;  (2)  identify  the  performance  obligations  in  the  contract;  (3)  determine  the  transaction  price;  (4)
allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the Company satisfies a
performance obligation.

106

Table of Contents

All of the Company’s revenue to date has been generated from its collaboration agreements, primarily its collaboration agreement
with Merck. The terms of these agreements generally require the Company to provide (i) license options for its compounds, (ii) research and
development,  or  R&D,  services  and  (iii)  non-mandatory  services  in  connection  with  participation  in  research  or  steering  committees.
Payments received under these arrangements may include non-refundable upfront license fees, partial or complete reimbursement of R&D
costs,  contingent  consideration  payments  based  on  the  achievement  of  defined  collaboration  objectives  and  royalties  on  sales  of
commercialized  products.  In  some  agreements,  the  collaboration  partner  is  solely  responsible  for  meeting  defined  objectives  that  trigger
contingent or royalty payments. Often the partner only pursues such objectives subsequent to exercising an optional license on compounds
identified as a result of the R&D services performed under the collaboration agreement.

The  Company  assesses  whether  the  promises  in  its  arrangements,  including  any  options  provided  to  the  partner,  are  considered
distinct  performance  obligations  that  should  be  accounted  for  separately.  Judgment  is  required  to  determine  whether  the  license  to  a
compound is distinct from R&D services or participation in research or steering committees, as well as whether options create material rights
in the contract. In situations when a contract includes distinct R&D services that are substantially the same and have the same pattern of
transfer to the customer over time, they are recognized as a series of distinct services.

The  transaction  price  in  each  arrangement  is  generally  comprised  of  a  non-refundable  upfront  fee  and  unconstrained  variable
consideration related to the performance of R&D services. The unconstrained variable consideration amount included in the transaction price
represents  an  amount  for  which  it  is  probable  that  a  significant  reversal  of  cumulative  revenue  recognized  will  not  occur.  The  Company
typically submits a budget for the R&D services to the partner in advance of performing the services. The transaction price is allocated to the
identified  performance  obligations  based  on  the  standalone  selling  price,  or  SSP,  of  each  distinct  performance  obligation.  Judgment  is
required  to  determine  the  SSP.  In  instances  where  the  SSP  is  not  directly  observable,  such  as  when  a  license  or  service  is  not  sold
separately,  SSP  is  determined  using  information  that  may  include  market  conditions  and  other  observable  inputs.  The  Company  utilizes
judgment to assess the nature of its performance obligations to determine whether they are satisfied over time or at a point in time and, if
over  time,  the  appropriate  method  of  measuring  progress  toward  completion.  The  Company  evaluates  the  measure  of  progress  each
reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.

The  Company’s  collaboration  agreements  may  include  contingent  payments  related  to  specified  development  and  regulatory
milestones or contingent payments for royalties based on sales of a commercialized product. Milestones can be achieved for such activities
in  connection  with  progress  in  clinical  trials,  regulatory  filings  in  various  geographical  markets  and  marketing  approvals  from  health
authorities. Sales-based royalties are generally related to the volume of annual sales of a commercialized product. At the inception of each
agreement  that  includes  such  payments,  the  Company  evaluates  whether  the  milestones  are  considered  probable  of  being  achieved  and
estimates  the  amount  to  be  included  in  the  transaction  price  by  using  the  most  likely  amount  method.  If  it  is  probable  that  a  significant
revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within
the  Company’s  or  its  partner’s  control,  such  as  those  related  to  regulatory  approvals,  are  not  considered  probable  of  being  achieved  until
those approvals are received. The transaction price is then allocated to each performance obligation based on a relative SSP basis. At the
end of each subsequent reporting period, the Company re-evaluates the probability of achievement of each such milestone and any related
constraint and, if necessary, adjusts its estimate of the overall transaction price. Pursuant to the guidance in ASC 606, sales-based royalties
are  not  included  in  the  transaction  price.  Instead,  royalties  are  recognized  at  the  later  of  when  the  performance  obligation  is  satisfied  or
partially satisfied, or when the sale that gives rise to the royalty occurs.

Contract  modifications,  defined  as  changes  in  the  scope  or  price  (or  both)  of  a  contract  that  are  approved  by  the  parties  to  the
contract,  such  as  a  contract  amendment,  exist  when  the  parties  to  a  contract  approve  a  modification  that  either  creates  new,  or  changes
existing, enforceable rights and obligations of the parties to the contract. Depending on facts and circumstances, the Company accounts for a
contract  modification  as  one  of  the  following:  (i)  a  separate  contract;  (ii)  a  termination  of  the  existing  contract  and  a  creation  of  a  new
contract; or (iii) a combination of the preceding treatments. A contract modification is accounted for as a separate contract if the scope of the
contract increases because of the addition of promised services that are distinct and if the price of the contract increases by an amount of
consideration that reflects the Company’s standalone selling prices of the additional promised services. When a contract modification is not
considered a separate contract and the remaining services are distinct from the services transferred on or before the date of the contract
modification, the Company accounts for the contract modification as a termination of the existing contract and a creation of a new contract.
When a contract modification is not considered a separate contract and the remaining services are not distinct, the

107

Table of Contents

Company  accounts  for  the  contract  modification  as  an  add-on  to  the  existing  contract  and  as  an  adjustment  to  revenue  on  a  cumulative
catch-up basis.

Research and Development

R&D costs are expensed as incurred. R&D expenses primarily include salaries and benefits for medical, clinical, quality, preclinical,
manufacturing and research personnel, costs related to research activities, preclinical studies, clinical trials, drug manufacturing expenses
and allocated overhead and facility occupancy costs. The Company accounts for non-refundable advance payments for goods or services
that will be used in future R&D activities as expenses when the goods have been received or when the service has been performed rather
than when the payment is made.

Clinical trial costs are a component of R&D expenses. The Company accrues estimated costs for its clinical trial activities performed
by third parties, including clinical research organizations, or CROs, and other service providers based upon estimates of the proportion of
work  completed  over  the  life  of  the  individual  clinical  trial  and  patient  enrollment  rates  in  accordance  with  associated  agreements.  The
Company's  estimates  are  determined  through  detailed  discussions  with  internal  personnel  and  its  service  providers  as  to  the  progress  of
each clinical trial and by reviewing contracts, vendor agreements and purchase orders for previously agreed-upon rates and fees to be paid
for such services.

Stock-Based Compensation

The Company’s stock-based compensation program includes awards made under the Company's 2018 Equity Incentive Plan, or the
2018  Plan,  and  the  2019  Employee  Stock  Purchase  Plan,  or  ESPP.  The  Company  measures  stock-based  compensation  expense  for  all
stock-based awards at the grant date based on the fair value measurement of the award. The expense is recorded on a straight-line basis
over the requisite service period, which is generally the vesting period, for the entire award. Forfeitures are estimated at the time of grant and
revised,  if  necessary,  in  subsequent  periods  if  actual  forfeitures  materially  differ  from  estimates.  The  Company  calculates  the  fair  value
measurement of stock options using the Black-Scholes option-pricing model.

Comprehensive Loss

Comprehensive loss is composed of net loss and certain changes in stockholders’ equity that are excluded from net loss, primarily

unrealized gains or losses, net of taxes, on the Company’s marketable securities.

Net Loss per Share

Basic net loss per share is calculated by dividing net loss by the weighted average number of shares outstanding during the period,
less  shares  subject  to  repurchase  and  excludes  any  dilutive  effects  of  stock-based  options  and  awards.  Diluted  net  income  per  share  is
computed by giving effect to all potentially dilutive shares, including common stock issuable upon exercise of stock options and the assumed
vesting of outstanding RSUs. However, where there is a diluted net loss per share, no adjustment is made for potentially issuable shares
since their effect would be anti-dilutive. In this case, diluted net loss per share is equal to basic net loss per share.

Net loss per share was computed as follows (in thousands, except per share amounts):

The  Company  operates  in  one  business  segment.  Substantially  all  of  the  Company’s  long-lived  assets,  primarily  comprised  of
property and equipment, are based in the United States. For the years ended December 31, 2023, 2022 and 2021, the Company’s revenues
were entirely within the United States based upon the location of the Company and Merck.

Recent Accounting Pronouncements

New  accounting  pronouncements  are  issued  by  the  Financial  Accounting  Standards  Board,  or  FASB,  or  other  standard  setting
bodies and adopted by the Company as of the specified effective date. Unless otherwise discussed, the impact of recently issued standards
that are not yet effective will not have a material impact on the Company’s results of operations and financial position upon adoption.

Recent Accounting Pronouncements Not Yet Adopted

In  December  2023,  the  FASB  issued  ASU  2023-09,  Income  Taxes  (Topic  740):  Improvements  to  Income  Tax  Disclosures.  The
guidance requires public business entities to disclose in their rate reconciliation table additional categories of information about federal, state
and  foreign  income  taxes  and  to  provide  additional  information  about  reconciling  items  that  meet  a  quantitative  threshold.  The  guidance
requires all entities to disclose annually income taxes paid (net of refunds received) disaggregated by federal (national), state and foreign
taxes  and  to  disaggregate  the  information  by  jurisdiction  based  on  a  quantitative  threshold.  For  public  business  entities,  the  guidance  is
effective for annual periods beginning after December 15, 2024. All entities should apply the guidance prospectively but have the option to
apply it retrospectively. Early adoption is permitted. The Company is currently assessing the timing of adoption and expects the adoption of
ASU 2023-09 will not have a material impact on its results of operations and financial position.

In  November  2023,  the  FASB  issued  ASU  2023-07,  Segment  Reporting  (Topic  280):  Improvements  to  Reportable  Segment
Disclosures. The guidance requires a public entity to disclose for each reportable segment, on an interim and annual basis, the significant
expense categories and amounts that are regularly provided to the chief operating decision-maker, or CODM, and included in each reported
measure of a segment’s profit or loss. Public entities with a single reportable segment are required to provide the new disclosures and all the
disclosures required under Accounting Standards Codification (ASC) Topic 280, Segment Reporting. Additionally, ASU 2023-07 requires a
public  entity  to  disclose  the  title  and  position  of  the  individual  or  the  name  of  the  group  or  committee  identified  as  the  CODM.  All  public
entities are required to explain in the notes to the financial statements how the CODM uses each reported measure of a segment’s profit or
loss  in  assessing  segment  performance  and  determining  how  to  allocate  resources.  The  guidance  is  effective  for  public  entities  for  fiscal
years  beginning  after  December  15,  2023,  and  interim  periods  within  fiscal  years  beginning  after  December  15,  2024.  Early  adoption  is
permitted. The guidance is applied retrospectively to all periods presented in the financial statements, unless it is impracticable. The segment
expense  categories  and  amounts  disclosed  in  the  prior  periods  should  be  based  on  the  significant  segment  expense  categories  identified
and disclosed in the period of adoption. The Company is currently assessing the timing of adoption and expects the adoption of ASU 2023-
07 will not have a material impact on its results of operations and financial position.

The cash and cash equivalents amount in the table above excludes cash on deposit with banks of $6.4 million and $10.6 million as of

December 31, 2023 and 2022, respectively.

To date, the Company has not recorded any impairment charges against the market value of its marketable securities. In determining
whether an investment is impaired, the Company considers various factors including the length of time and extent to which the market value
has  been  less  than  cost,  the  financial  condition  and  near-term  prospects  of  the  issuer  and  the  Company’s  intent  and  ability  to  retain  its
investment in the issuer for a time period sufficient to allow for any anticipated recovery in market value.

As of December 31, 2023 and 2022, all of the Company’s marketable securities had remaining contractual maturities of less than
one year. As of December 31, 2023, the Company had nine marketable securities in an unrealized loss position compared to 19 marketable
securities  in  an  unrealized  loss  position  as  of  December  31,  2022.  Marketable  securities  that  were  in  unrealized  loss  positions  as  of
December 31, 2023 and 2022 had been in an unrealized loss position for less than twelve months. The Company does not need to, nor does
it intend to, sell marketable securities that are in an unrealized loss position, and it is highly unlikely that the Company will be required to sell
the investments before recovery of their amortized cost basis, which may be maturity.

5. Research Collaboration and License Agreements

Merck

In  2015,  the  Company  entered  into  a  research  collaboration,  product  development  and  license  agreement  with  Merck,  which,
together  with  amendments  made  prior  to  June  30,  2021,  is  referred  to  as  the  Original  Collaboration  Agreement,  covering  the  discovery,
development and commercialization of novel therapies across a range of therapeutic areas, including a broad, multi-year drug discovery and
early development program that was financially supported by Merck, and scientifically directed by the Company with input from Merck. The
original research program term of the collaboration was for five years and was extended by Merck for an additional two years through March
2022. As part of that extension, Merck agreed to continue to fund up to $75.0 million of the Company's R&D efforts each year consistent with
the  initial  five-year  research  term  and,  in  lieu  of  a  $20.0  million  extension  fee  payable  to  the  Company,  Merck  agreed  to  make  additional
payments totaling up to $20.0 million in support of the Company's R&D activities during 2021 through the first quarter of 2022.

On  June  30,  2021,  the  Company  entered  into  an  amended  and  restated  research  collaboration,  product  development  and  license
agreement  with  Merck,  or  the  Amended  Collaboration  Agreement,  replacing  the  Original  Collaboration  Agreement  and  extending  the
research program term of the collaboration generally through March 31, 2024, with possible extensions for each of the various programs to
allow  the  Company  or  Merck  to  complete  ongoing  development,  but  with  a  narrower  scope  than  in  the  Original  Collaboration  Agreement.
Under  the  Amended  Collaboration  Agreement,  the  collaboration  was  focused  primarily  on  the  identification,  research  and  development  of
collaboration  compounds  directed  to  targets  of  interest  to  Merck  in  the  fields  of  ophthalmology  and  cardiovascular  or  metabolic,  or  CVM,
disease, including heart failure. The collaboration scope also included certain laboratory testing

112

Table of Contents

and other activities on compounds that are directed to one of up to two undisclosed targets outside of the fields of ophthalmology and CVM
disease, or the Lab Programs.

Currently, the only ongoing research activities to be funded under the Amended Collaboration Agreement are certain CVM-related
activities. The research program term for the CVM-related continuing programs will continue until March 31, 2024, unless the parties mutually
agree to extend the research program term to March 31, 2026, in which case Merck would provide up to a total of $20.0 million in research
funding during those additional two years. The Company does not expect the research program term to be extended. Remaining activities
under the Lab Programs were substantially completed in the first quarter of 2023. The ophthalmology compounds in the collaboration under
the  Amended  Collaboration  Agreement  initially  included  NGM621  (and  its  related  compounds)  and  compounds  directed  against  two  other
undisclosed ophthalmology targets (and their related compounds). Merck had a one-time option to license NGM621, its related compounds
and the ophthalmology bundle upon completion of the Phase 2 CATALINA trial. In December 2022, Merck notified the Company that it would
not exercise its option to license NGM621 and its related compounds, nor would Merck exercise the related ophthalmology bundle option;
accordingly, these options expired unexercised in January 2023 and the programs are now wholly-owned by the Company. Further, Merck
did not elect for the Company to continue to conduct R&D during an extended or tail period on any compounds from the Company's other
ophthalmology programs that were subject to the collaboration. Because Merck did not exercise its ophthalmology license options or make
an R&D tail period election, the programs are now wholly-owned by the Company and the Company does not have any funding from Merck
to pursue such ophthalmology programs.

Pursuant to the Amended Collaboration Agreement, the Company gained the right, in its sole discretion, to independently research,
develop  and  commercialize  the  collaboration  compounds  known  as  NGM707,  NGM120,  NGM438  and  NGM831,  their  related  compounds
and all other preclinical and research assets that the Company researched or developed under the Original Collaboration Agreement but that
were  not  included  within  the  R&D  scope  of  the  continuing  collaboration,  which  are  referred  to  as  the  released  NGM  compounds.  Merck
retained the right to receive royalties at low single-digit rates on the sales of any released NGM compounds that receive regulatory approval
and,  if  the  Company  decides  during  a  certain  time  period  to  engage  in  a  formal  partnering  process  for  a  released  NGM  compound  or
negotiations regarding a license or asset sale of a released NGM compound, the Company is obligated to notify Merck, provide Merck with
certain  information  and  engage  in  good  faith,  non-exclusive  negotiations  with  respect  to  such  released  NGM  compound  with  Merck  at
Merck’s request.

Under  the  Amended  Collaboration  Agreement,  Merck  continued  to  have  a  Merck  license  option,  as  it  did  under  the  Original
Agreement,  to  each  continuing  collaboration  compound  that  is  identified,  researched  and  developed  under  the  Amended  Collaboration
Agreement and reaches the specified option exercise point for such continuing collaboration compound as described below, and to its related
compounds (each such continuing collaboration compound and its related compounds are referred to generally as a continuing program). In
addition,  under  the  terms  of  the  Amended  Collaboration  Agreement,  new  CVM-related  programs  may  be  added  to  the  continuing
collaboration if recommended by the Company and selected by Merck, and Merck would have a Merck license option to such CVM-related
continuing program. We do not expect any new CVM-related programs to be added to the collaboration.

The Merck license option exercise point for a continuing collaboration compound from the CVM-related continuing programs or the
Lab Programs will be the designation by Merck of such continuing collaboration compound as a research program development candidate
that Merck intends to progress into preclinical development.

Under the Amended Collaboration Agreement, if Merck exercises the Merck license option for a continuing collaboration compound
from a CVM-related continuing program or the Lab Programs, Merck will pay the Company a $6.0 million option exercise fee at the time of
selection to progress such licensed continuing collaboration compound or any of its related compounds into preclinical development and an
additional  $10.0  million  milestone  payment  if  such  continuing  collaboration  compounds  or  one  of  its  related  compounds  subsequently
completes  a  human  proof-of-concept  trial.  Merck  will  be  responsible,  at  its  own  cost,  for  any  further  development  and  commercialization
activities for continuing collaboration compounds within any such licensed continuing program.

In March 2022, the Company and Merck entered into a letter agreement, or the Letter Agreement, regarding NGM621 manufacturing
activities that the Company undertook with the intention of avoiding a significant delay between the completion of the CATALINA trial and the
start of any Phase 3 clinical trial for NGM621.

Under the Amended Collaboration Agreement, Merck provided $86.0 million in research funding for the four calendar quarters that
ended on March 31, 2022, which included the remaining $16.0 million of the up to $20.0 million in additional payments Merck agreed to pay
as part of exercising its first option to extend the research

113

Table of Contents

program  term  of  the  collaboration  under  the  Original  Collaboration  Agreement  for  two  years  through  March  16,  2022.  The  Company  was
obligated to use commercially reasonable efforts to expend, and did spend, at least $35.0 million of such $86.0 million in funding for the four
calendar quarters that ended on March 31, 2022 on the ophthalmology and CVM-related programs and Lab Programs as required under the
Amended Collaboration Agreement. The Company was permitted to use the remainder of the $86.0 million in research funding provided by
Merck during such time frame to advance the released NGM compounds. Pursuant to the Letter Agreement, the Company also used part of
this research funding to cover the costs of its personnel who provided support for the manufacturing activities that the Company undertook in
preparation  for  a  potential  Phase  3  clinical  trial  for  NGM621  and  Merck  reimbursed  the  Company  the  maximum  reimbursable  amount  for
NGM621  third-party  manufacturing  costs  of  $4.75  million.  Merck  also  funded  certain  costs  and  reimbursements  related  to  the  NGM621
program in 2022 and in 2023.

The  Company  concluded  that  the  Amended  Collaboration  Agreement  is  a  separate  arrangement  containing  a  three-year
performance  obligation  to  provide  distinct  R&D  services  in  accordance  with  ASC  606.  The  total  transaction  price  under  the  Amended
Collaboration  Agreement  is  $119.0  million  which  includes  $86.0  million  in  research  funding  for  the  four  calendar  quarters  that  ended  on
March 31, 2022, $15.1 million in research funding for the ophthalmology and CVM-related continuing programs and the Lab Programs during
the  remaining  two  years  of  the  research  program  term  after  March  2022,  $13.1  million  in  estimated  NGM621  reimbursable  expenses  and
costs  during  the  remaining  two  years  of  the  research  program  term  after  March  2022  and  $4.75  million  for  reimbursable  amounts  paid  in
2022  to  a  third-party  manufacturer  in  accordance  with  the  terms  of  the  Letter  Agreement.  The  Company  will  continue  to  re-evaluate  the
transaction  price  as  uncertain  events  are  resolved  or  other  changes  in  circumstances  occur.  The  Company  continues  performing  its  R&D
services in the area of both the continuing collaboration compounds and the released NGM compounds and has one performance obligation
across  all  continuing  programs.  The  Company  will  continue  to  use  the  cost-based  input  method  to  calculate  the  amount  of  revenue  to
recognize as services are being rendered from April 1, 2021 through March 31, 2024. For the first half of 2024, the Company expects Merck
will provide minimal funding and this amount is included in the transaction price.

The  Company  considered  whether  the  Merck  license  option  created  material  rights  in  the  contract  and  concluded  that  the  fee
attached to the exercise of such options approximated the SSP of the promised goods or services included in the options. Therefore, the
Company concluded that such options did not give rise to material rights, were not performance obligations in the Amended Collaboration
Agreement and, if and when exercised, would be accounted for as separate arrangements under ASC 606.

Merck owned approximately 16% of the Company's outstanding shares as of December 31, 2023.

Summary of Related Party Revenue

The Company recognized revenue from its collaboration and license agreements as follows (in thousands):

$

4,417  $

For the years ended December 31, 2023 and 2022, the Company recognized collaboration and license revenue primarily related to
reimbursable R&D activities associated with the performance obligation under the Amended Collaboration Agreement under which Merck is
providing  significantly  less  annual  R&D  funding  than  it  had  provided  through  March  31,  2022.  Related  party  revenue  related  to  the
reimbursable R&D activities was recognized using the cost-based input model related to R&D activities.

For  the  year  ended  December  31,  2021,  the  Company  recognized  collaboration  and  license  revenue  primarily  related  to
reimbursable R&D activities associated with the performance obligation for the two-year extension period through March 31, 2021 under the
Original Collaboration Agreement and from April 1, 2021 through December 31, 2021 under the Amended Collaboration Agreement, all of
which were recognized using the cost-based input model.

Related Party Contract Assets and Liabilities

Amounts  recognized  as  revenue  prior  to  the  Company  having  an  unconditional  right  (or  a  right  that  is  conditioned  only  on  the
passage of time) to receipt are recorded as contract assets in the Company's consolidated balance sheets. If the Company expects to have
an unconditional right to receive the consideration in the next

114

Table of Contents

twelve  months,  the  contract  asset  will  be  classified  in  current  assets.  As  of  December  31,  2023  and  2022,  the  Company  did  not  have  a
related party contract asset.

Amounts  received  prior  to  satisfying  the  revenue  recognition  criteria  are  recorded  as  contract  liabilities  in  the  Company’s
consolidated  balance  sheets.  If  the  related  performance  obligation  is  expected  to  be  satisfied  within  the  next  twelve  months,  the  contract
liability will be classified in current liabilities. As of December 31, 2023, the Company did not have a contract liability. As of December 31,
2022, the Company recorded a contract liability in current liabilities of $0.4 million.

6.    Commitments and Contingencies

Operating Leases and Lease Guarantee

In  December  2015,  the  Company  entered  into  an  operating  lease  agreement,  or  the  333  Oyster  Point  lease  agreement,  for  its
corporate  office  and  laboratory  space  at  333  Oyster  Point  Blvd.,  South  San  Francisco,  California,  or  the  333  Oyster  Point  facility,  for
approximately  122,000  square  feet  that  expired  on  December  31,  2023.  The  333  Oyster  Point  lease  agreement  provided  a  tenant
improvement  allowance  of  $15.2  million  that  the  Company  used  in  2016  towards  $22.3  million  in  total  leasehold  improvements  that  were
amortized over the lease term of seven years. As of December 31, 2023, restricted cash in current assets on the Company's consolidated
balance sheets included a letter of credit in the amount of $1.5 million required under the 333 Oyster Point lease agreement.

Cash  paid  for  amounts  included  in  the  measurement  of  the  lease  liabilities  were  $5.5  million  and  $5.3  million  for  the  years

ended December 31, 2023 and 2022, respectively.

During  the  years  ended  December  31,  2023  and  2022,  the  components  of  lease  costs,  which  were  included  in  general  and

administrative expenses on the Company's consolidated statements of operations, were as follows (in thousands):

(1) Variable lease costs include certain additional charges for operating costs, including insurance, maintenance, taxes and other costs incurred, which are billed based on both
usage and as a percentage of the Company’s share of total square footage.

In July 2022, the Company entered into an operating lease agreement, or the 2024 Lease Agreement, for its corporate office and
laboratory space at 333 Oyster Point Blvd., South San Francisco, California, which the Company occupied pursuant to the 333 Oyster Point
lease  agreement  through  December  31,  2023.  Pursuant  to  the  2024  Lease  Agreement,  the  lease  term  with  the  new  landlord  began  on
January 1, 2024 (the lease commencement date) and expires on December 31, 2033, and the Company will pay an initial monthly base rent
of  approximately  $0.9  million  for  the  first  year,  which  is  subject  to  increase  at  an  annual  rate  of  3.5%  each  year  thereafter,  plus  certain
operating and tax expenses. Base rent for the initial ten-year term of the 2024 Lease Agreement amounts to $124.1 million. The 2024 Lease
Agreement provides a tenant improvement allowance of approximately $4.9 million. The Company has an option to extend the 2024 Lease
Agreement  for  a  period  of  either  eight  years  or  ten  years  after  the  initial  term.  In  July  2022,  pursuant  to  the  2024  Lease  Agreement,  the
Company provided the landlord with a letter of credit in the amount of $2.5 million, that was reported as restricted cash in non-current assets
on the Company's consolidated balance sheets as of December 31, 2023 and 2022, respectively.

Indemnification

In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and
warranties and may provide for indemnification of the counterparty. The Company’s exposure under these agreements is unknown because it
involves claims that may be made against it in the future but have not yet been made.

In  accordance  with  the  Company’s  amended  and  restated  certificate  of  incorporation  and  its  amended  and  restated  bylaws,  the
Company has indemnification obligations to its officers and directors, subject to some limits, with respect to their service in such capacities.
The Company has also entered into indemnification agreements with its directors and certain of its officers. To date, the Company has not
been subject to any claims, and it maintains director and officer insurance that may enable it to recover a portion of any amounts paid for
future potential claims.

115

Table of Contents

The Company’s exposure under these agreements is unknown because it involves claims that may be made against it in the future
but have not yet been made. The Company believes that the fair value of these indemnification obligations is minimal and, accordingly, it has
not recognized any liabilities relating to these obligations for any period presented.

7. Stockholders’ Equity

Preferred Stock

The Company has 10.0 million shares of preferred stock authorized, which may be issued at the discretion of the Company’s board
of directors. The board of directors may issue shares of preferred stock in one or more series and may fix the number, rights, preferences,
privileges and restrictions on such shares. These rights, preferences and privileges could include dividend rights, conversion rights, voting
rights,  terms  of  redemption,  liquidation  preferences  and  sinking  fund  terms.  As  of  December  31,  2023,  the  Company  does  not  have  any
shares of preferred stock issued or outstanding.

Common Stock

Public Offering of Common Stock

In January 2021, the Company sold 5.3 million shares of its common stock through an underwritten public offering at a price to the
public  of  $27.00  per  share  for  aggregate  net  proceeds  to  the  Company  of  $134.6  million,  after  deducting  underwriting  discounts  and
commissions and other offering expenses paid by the Company. The offering closed on January 8, 2021.

As  of  December  31,  2023  and  2022,  the  Company  had  82.9  million  and  81.9  million  shares  of  common  stock  outstanding,

respectively.

In June 2020, the Company entered into the Sales Agreement with Jefferies pursuant to which the Company could sell, from time to
time, through or to Jefferies, up to an aggregate of $150.0 million of the Company’s common stock. In June 2023, the Company entered into
the Amended Sales Agreement. In connection with the Amendment, the Company filed a new shelf registration statement on Form S-3 which
the SEC declared effective in August 2023. The Amended Sales Agreement provides for the issuance and sales of shares of the Company's
common  stock  having  an  aggregate  offering  price  of  up  to  $100.0  million  through  or  to  Jefferies.  As  of  December  31,  2023,  up  to
$100.0 million of the Company's common stock remained available to be sold under the Amended Sales Agreement, subject to conditions
specified in the Amended Sales Agreement.

Equity Incentive Plan

In 2018, the Company adopted the 2018 Plan for eligible employees, officers, directors, advisors and consultants, which provides for
the grant of incentive and non-statutory stock options, restricted stock awards and stock appreciation rights. The terms of the stock option
agreements, including vesting requirements, are determined by the board of directors, subject to the provisions of the 2018 Plan. Options
granted  by  the  Company  generally  vest  within  four  years  and  are  exercisable  from  the  grant  date  until  ten  years  after  the  date  of  grant.
Vesting of certain employee options may be accelerated in the event of a change in control of the Company. Pursuant to the terms of the
2018 Plan, the number of shares reserved and available to issue will automatically increase on January 1st of each year in an amount equal
to 4% of the total number of shares of common stock outstanding on the

116

Table of Contents

December  31st  immediately  preceding  calendar  year,  unless  the  board  of  directors  elects  to  forego  or  reduce  such  increase.  As  of
December 31, 2023, 22.8 million shares of common stock had been authorized for issuance under the 2018 Plan and the Company's 2008
Equity Incentive Plan which expired in 2018.

Stock options are governed by stock option agreements between the Company and recipients of stock options. The exercise price of
each option may not be less than 100% of the fair market value of the common stock subject to the option on the date the option is granted.
A 10% or greater stockholder may not be granted an incentive stock option unless the exercise price of such option is at least 110% of the
fair value of the common stock on the date of grant and the option is not exercisable after the expiration of five years from the grant date.
Options  become  exercisable  and  expire  as  determined  by  the  Company's  Compensation  Committee,  or  the  Committee,  of  the  Board  of
Directors, or the Board, provided that the term of incentive stock options may not exceed ten years from the date of grant for options granted

In 2019, the Company adopted the ESPP. The Company reserved 1.0 million shares of common stock pursuant to purchase rights
granted to the Company’s employees. The ESPP provides that the number of shares reserved and available for issuance will automatically
increase  on  January  1  of  each  calendar  year  by  the  lesser  of  (1)  1%  of  the  total  number  of  shares  of  common  stock  outstanding  on
December 31 of the preceding calendar year, (2) 1.0 million shares or (3) a number determined by the Company’s board of directors that is
less than (1) and (2). Under the ESPP, eligible employees are granted the right to purchase shares of the Company’s common stock through
payroll deductions that cannot exceed 15% of each employee’s salary. The ESPP provides for a 24-month offering period, which includes
four six-month purchase periods. At the end of each purchase period, eligible employees are permitted to purchase shares of common stock
at the lower of 85% of fair market value at the beginning of the offering period or fair market value at the end of the purchase period. The
ESPP is considered a compensatory plan. As of December 31, 2023, 1.3 million shares of common stock had been purchased under the
ESPP.

Restricted Stock Units

During  the  year  ended  December  31,  2023,  the  Company  granted  1.0  million  RSUs  covering  an  equal  number  of  shares  of  the
Company's  common  stock  to  employees  with  a  weighted-average  grant  date  fair  value  of  $4.36  per  RSU.  The  fair  value  of  RSUs  is
determined on the date of grant based on the market price of the Company's common stock as of that date. The fair value of the RSUs is
recognized  as  an  expense  ratably  over  the  vesting  period  of  four  years.  As  of  December  31,  2023,  no  shares  underlying  the  RSUs  had
vested or been released and 0.4 million shares had been forfeited .

Stock Option Activity

Repricing Program

On  October  17,  2023,  the  Committee  approved  an  option  repricing  program,  or  the  repricing  program,  which  was  effective  on
November 6, 2023, or the Effective Date. The repricing program generally applies to options to purchase shares of the Company’s common
stock that: (i) were granted under the Company’s equity incentive plans; (ii) as of the Effective Date, are held by the Company’s then-current
employees  (subject  to  the  retention  requirements  below);  and  (iii)  have  an  exercise  price  per  share  greater  than  $5.00.  Such  options  are
referred to as the Eligible Options. The Eligible Options include options held by certain of the Company's executive officers. Options held by
nonemployee members of the Board are not eligible for the repricing program.

As of the Effective Date, the Eligible Options were immediately repriced such that the exercise price per share for such options was
reduced to the closing price of the Company’s common stock on the Effective Date, subject to certain retention requirements outlined below.
The closing price of the Company’s common stock was $0.84 and became the reduced exercise price for the Eligible Options. If an employee
exercises Eligible Options in advance of the end of the retention period as described below, the employee will be required to pay a premium
exercise price equal to the original exercise price per share of the Eligible Options. The Eligible Options that were previously incentive stock
options were amended to become nonstatutory stock options on or following the Effective Date. There were no changes to the number of
shares underlying the Eligible Options or to the vesting schedules or expiration dates of the Eligible Options.

In  order  to  exercise  the  Eligible  Options  at  the  reduced  exercise  price,  holders  of  the  Eligible  Options  are  required  to  remain  in
service with the Company through the end of the relevant retention period. The retention period begins on the Effective Date and ends on the
earliest of the following: (i) the date 12 months (or, in the case

117

Table of Contents

of the Eligible Options held by the Company's Chief Executive Officer that are unvested as of the Effective Date, 18 months) following the
Effective  Date;  (ii)  a  Change  in  Control  (as  defined  in  the  applicable  equity  incentive  plan)  if  the  Eligible  Options  are  not  assumed  or
continued  by  the  successor  or  acquiror  entity  (or  its  parent  company)  in  such  Change  in  Control  or  substituted  for  a  similar  award  of  the
successor  or  acquiror  entity  (or  its  parent  company);  and  (iii)  the  optionholder’s  termination  of  Continuous  Service  (as  defined  in  the
applicable  equity  incentive  plan)  (a)  due  to  such  individual’s  death  or  disability,  (b)  by  the  Company  (or  successor  entity  in  a  Change  in
Control) other than for Cause (as defined in the applicable equity incentive plan) or (c) due to such optionholder’s resignation on or following
a Change in Control under certain circumstances.

As of the Effective Date, the total number of shares underlying all Eligible Options was 6.9 million shares. The effect of the repricing
resulted  in  total  incremental  stock-based  compensation  expense  of  $2.1  million,  $1.9  million  of  which  will  be  recognized  on  a  straight-line
basis through the end of each of the applicable retention periods, while the remaining $0.2 million will be recognized on a straight-line basis
over  the  original  vesting  period  for  those  options  that  vest  after  the  end  of  each  applicable  retention  period.  The  incremental  stock-based
compensation expense was calculated using the lattice option-pricing model.

For  the  year  ended  December  31,  2023,  the  Company  recognized  incremental  stock-based  compensation  expense  totaling
$0.3 million associated with the repricing program, which is included in general and administrative and research and development expense
on the consolidated statement of operations.

Valuation Assumptions

The Company uses the Black-Scholes option-pricing model to estimate the fair value of stock options at the grant date. The Black-
Scholes  option-pricing  model  requires  the  Company  to  make  certain  estimates  and  assumptions,  including  assumptions  related  to  the
expected  price  volatility  of  the  Company’s  stock,  the  period  during  which  the  options  will  be  outstanding,  the  rate  of  return  on  risk-free
investments and the expected dividend yield for the Company’s stock.

The  expected  volatility  is  based  on  the  historical  volatility  of  the  Company's  stock  and  the  stock  of  similar  entities  within  the
Company’s industry over periods commensurate with the Company’s expected term assumption. The expected term of stock option grants
represents the weighted-average period the options are expected to remain outstanding and is based on the “simplified” method where the
expected term is the midpoint between the vesting date and the end of the contractual term for each option. The Company bases the risk-
free interest rate on the interest rate payable on U.S. Treasury securities in effect at the time of grant for a period that is commensurate with
the assumed expected option term. In reference to the expected dividend yield assumption, the Company has not historically paid, and does
not expect for the foreseeable future to pay, a dividend.

The weighted average grant-date fair value of stock options granted during the years ended December 31, 2023, 2022 and 2021 was
$2.87, $8.63 and $18.57 per share, respectively. The intrinsic value of stock options exercised was $1.0 million, $3.2 million and $34.2 million
for  the  years  ended  December  31,  2023,  2022  and  2021,  respectively.  Due  to  the  Company’s  net  operating  losses,  the  Company  did  not
realize any tax benefits from stock-based payment arrangements for the years ended December 31, 2023, 2022 and 2021.

The fair value of stock option awards granted to employees and directors was estimated at the date of grant using a Black-Scholes

option-pricing model with the following weighted average valuation assumptions:

The  Company  sponsors  a  401(k)  defined  contribution  plan  for  its  employees.  Employee  contributions  are  voluntary.  In  December
2011,  the  Company  adopted  the  401(k)  Matching  Plan,  under  which  the  Company  makes  matching  contributions  in  the  form  of  common
stock  at  a  rate  of  $1.00  for  each  $2.00  of  employee  contributions  up  to  a  maximum  of  $3,500  of  common  stock  per  employee  per  year
beginning in 2022 and $750 prior to 2022. As of December 31, 2023 and 2022, the Company had reserved 64,975 and 192,385 shares of
common stock for issuance pursuant to the 401(k) Matching Plan, respectively. Matching contributions of 127,410, 7,615 and 4,117 shares,
or $639,000, $137,000 and $125,000 were issued for the years ended December 31, 2023, 2022 and 2021, respectively.

9. Workforce Reduction

During  the  second  quarter  of  2023,  the  Company  announced  and  substantially  completed  a  restructuring  of  the  Company's
workforce  pursuant  to  which  the  Company’s  workforce  was  reduced  by  74  people,  or  approximately  33%  of  the  Company’s  existing
headcount as of April 3, 2023. The Company incurred approximately $4.9 million in restructuring charges in connection with the restructuring,
consisting of (i) approximately $4.2 million in cash-based expenses related to employee severance and notice period payments, benefits and
related  costs,  and  (ii)  approximately  $0.7  million  in  noncash  stock-based  compensation  expense  related  to  the  vesting  of  stock-based
awards.

ASC  740  requires  that  the  tax  benefit  of  net  operating  losses,  temporary  differences  and  credit  carryforwards  be  recorded  as  an
asset to the extent that management assesses that realization is “more likely than not.” Realization of the future tax benefits is dependent on
the  Company’s  ability  to  generate  sufficient  taxable  income  within  the  carryforward  period.  Because  of  the  Company’s  recent  history  of
operating losses, management believes that recognition of the deferred tax assets arising from the above-mentioned future tax benefits is
currently not more-likely-than-not to be realized and, accordingly, has provided a valuation allowance.

Realization  of  deferred  tax  assets  is  dependent  upon  future  earnings,  if  any,  the  timing  and  amount  of  which  are  uncertain.
Accordingly, the net deferred tax assets have been fully offset by a valuation allowance. The valuation allowance increased by approximately
$26.0 million and $22.8 million during the years ended December 31, 2023 and 2022, respectively.

As  of  December  31,  2023,  the  Company  had  approximately  $382.3  million  in  federal  net  operating  loss  carryforwards  to  reduce
future taxable income. Of this amount, $329.8 million was generated after December 31, 2017 and can be carried forward indefinitely. The
federal net operating loss carryforwards generated prior to January 1, 2018 are subject to a 20-year carryforward period and will begin to
expire after 2032. The utilization of the federal net operating loss carryforwards generated in fiscal year 2018 and onwards is limited to 80%
of the federal taxable income. The Company also had approximately $592.5 million in state net operating loss carryforwards to reduce future
taxable income, which will begin to expire after 2028, if not utilized.

In accordance with the 2017 Tax Act, research and experimental, or R&E, expenses under Internal Revenue Code Section 174 are
capitalized beginning in 2022. R&E expenses are required to be amortized over a period of five years for domestic expenses and 15 years
for foreign expenses.

The Company had approximately $10.3 million and $3.1 million in federal R&D tax credits for the years ended December 31, 2023
and 2022, respectively. In addition, the Company had approximately $5.7 million and $4.0 million in state R&D tax credits for the years ended
December 31, 2023 and 2022, respectively. The federal research credits will begin to expire in the years 2028 through 2035, if not utilized.
The state R&D credits have no expiration date and can be carried forward indefinitely.

The Company had no foreign net operating loss carryforwards for each of the years ended December 31, 2023 and 2022.

Utilization of the Company’s net operating losses and R&D tax credits may be subject to a substantial annual limitation due to the
“change in ownership” provisions of the Internal Revenue Code of 1986, as amended, and similar state provisions. The annual limitation may
result in the expiration of net operating losses and R&D tax credits before utilization. The Company has not completed an ownership change
analysis pursuant to IRC Section

121

Table of Contents

382 as of December 31, 2023. If ownership changes within the meaning of IRC Section 382 are identified as having occurred, the amount of
remaining  net  operating  loss  carryforwards  available  to  offset  future  taxable  income  and  income  tax  expense  in  future  years  may  be
significantly restricted.

The entire amount of the unrecognized tax benefits would not impact the Company’s effective tax rate if recognized. The Company
has  elected  to  include  interest  and  penalties  as  a  component  of  tax  expense.  During  the  years  ended  December  31,  2023  and  2022,  the
Company did not recognize accrued interest and penalties related to unrecognized tax benefits. The Company does not anticipate that the
amount of existing unrecognized tax benefits will significantly increase or decrease during the next 12 months.

The Company files U.S. federal, state and foreign income tax returns with varying statutes of limitations. The tax years from inception

in 2008 to December 31, 2023 remain subject to examination.

Item 9A. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

As of December 31, 2023, management, with the participation of our Chief Executive Officer and Chief Financial Officer, performed
an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rules 13a-15(e) and
15d-15(e) of the Securities Exchange Act of 1934, as amended, or the Exchange Act. Our disclosure controls and procedures are designed
to  ensure  that  information  required  to  be  disclosed  in  the  reports  we  file  or  submit  under  the  Exchange  Act  is  recorded,  processed,
summarized  and  reported  within  the  time  periods  specified  in  the  SEC’s  rules  and  forms,  and  that  such  information  is  accumulated  and
communicated  to  our  management,  including  the  Chief  Executive  Officer  and  Chief  Financial  Officer,  to  allow  timely  decisions  regarding
required disclosures.

Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the
desired control objective and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and
procedures. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, 2023, the
design and operation of our disclosure controls and procedures were effective at a reasonable assurance level.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-
15(f)  and  15d-15(f)  of  the  Exchange  Act  that  occurred  during  the  quarter  ended  December  31,  2023  that  has  materially  affected,  or  is
reasonably likely to materially affect, our internal control over financial reporting.

Hsiao D. Lieu, M.D.

Dear Hsiao,

On behalf of NGM Biopharmaceuticals, Inc. (“NGM” or the “Company”), we are pleased that you will be joining the Company as Senior Vice
President, Chief Medical Officer reporting to me. We believe this position represents an extraordinary opportunity, and we look forward to
your joining our exceptional team.

Below are details of the compensation and benefits program we are offering as part of your employment with NGM, as well as other terms of
your employment. Should you have questions regarding any part of this offer, or wish to receive additional details, please let us know. Your
annual base salary will be $420,000.00, less payroll deductions and all required withholdings, paid semi-monthly over 24 pay periods per
year. In addition, you will be eligible to participate in the NGM Incentive Bonus Plan. You will also be eligible to receive a one-time sign-on
bonus of $225,000.00, payable within the first two pay periods of your employment with NGM. Should you voluntarily resign from NGM within
two (2) years from your start date, you will be required to repay the pro-rated portion of the sign-on bonus payment based on the number of
months you were employed by the Company following receipt of the sign-on bonus payment.

NGM provides all eligible employees with a comprehensive benefits program. You will have the opportunity to participate in these benefits,
which include medical, dental and vision coverage for you and your eligible dependents, if you choose to enroll in them. In addition, we
provide life insurance, LTD and AD&D coverage, along with a comprehensive 401(k) program. NGM also provides benefits including
Company holidays, vacation, sick leave and Health Care and Dependent Flexible Spending Accounts. The Company may change
compensation and benefits from time to time in its discretion. There is a formal performance review period once a year.

An important component of your compensation includes the opportunity for ownership in the Company. After you commence employment,
and subject to the approval of our Board of Directors (the “Board”), NGM will grant you an option to purchase 400,000 shares of the
Company’s common stock (subject to adjustment for stock splits, stock dividends, reclassification and the like) at the fair market value
determined by the Board as of the date of grant (the “Option”). The Option will be subject to the terms and conditions of the Company’s
Equity Incentive Plan (the “Plan”) and your grant agreement. Your grant agreement will reflect a four year vesting schedule, under which 25%
of your Option will vest after 12 months and 1/48th of the total will vest at the end of each month thereafter, until either the Option is fully
vested or your employment ends, whichever occurs first.

As a condition of your employment, you will be required to abide by the Company’s policies and procedures, including those outlined in our
employee handbook. You also agree to read, sign and comply with the Company’s Employee Proprietary Information and Inventions
Agreement (“Proprietary Information Agreement”).

In your work for the Company, you will be expected to not make any unauthorized use of, or disclose, the confidential information or
materials, including trade secrets, of any former employer or other third party to whom you owe an obligation of confidentiality. Rather, you
will be expected to use only that information generally known and used by persons with training and experience comparable to your own,
which information is common knowledge in the industry or otherwise legally available in the public domain, or which is otherwise provided or
developed by the Company. By accepting employment with the Company, you are representing to us that you will be able to perform your
duties within the guidelines described in this paragraph. You represent further that you have disclosed to the Company any contract you have
signed that may restrict your activities on behalf of the Company in any manner.

This offer is contingent upon our verification of your employment history. Any intentional misrepresentation concerning your employment
history may result in actions up to and including revocation of this offer or termination of your employment at NGM.

Your employment relationship is at-will. Accordingly, you may terminate your employment with the Company at any time and for any reason
whatsoever simply by notifying the Company. Likewise, the Company may terminate your employment at any time and for any reason, with
or without cause or advance notice.

This letter, together with your Proprietary Information Agreement, forms the complete and exclusive statement of your agreement with the
Company concerning this offer. The terms of this letter supersede any other representations or agreements made to you by any party,
whether oral or written. The terms of our agreement cannot be changed (except those changes expressly reserved to the Company’s
discretion in this letter) other than by a written agreement signed by you and a duly authorized officer of the Company. This agreement is to
be governed by the laws of the state of California without reference to its conflicts of law principles. In case any provision contained in this
agreement shall, for any reason, be held invalid or unenforceable in any respect, such invalidity or unenforceability will not affect the other
provisions of this agreement, and such provision will be construed and enforced so as to render it valid and enforceable consistent with the
general intent of the parties insofar as possible under applicable law. With respect to the enforcement of this agreement, no waiver of any
right hereunder will be effective unless it is in writing. This agreement may be executed in more than one counterpart, and signatures
transmitted electronically will be deemed equivalent to originals. As required by law, this offer is subject to satisfactory proof of your identity
and right to work in the United States.

Hsiao, we are thrilled that you have decided to accept our employment offer. Under the terms described above, please sign and date this
letter and the Proprietary Information Agreement, and return them by January 23, 2019. It is our expectation that you will join NGM in March
2019.

NGM is an ambitious undertaking, and we fully expect our company to become a force in the development and commercialization of
pharmaceutical therapies. To this end, we are assembling a team of uniquely qualified individuals with extraordinary knowledge, skills and
drive. Your leadership of the development area will be a critical part of our success and we look forward to you joining our team.

Sincerely,

/s/ David J. Woodhouse
David J. Woodhouse, Ph.D.

ADDITIONAL INFORMATION REGARDING SEVERANCE AND CHANGE IN CONTROL ARRANGEMENTS

In addition to the employment offer letter with Dr. Lieu entered into on January 16, 2019, in February 2023, the Compensation

Committee of the NGM Biopharmaceuticals, Inc. Board of Directors determined that, in the event of a termination without cause (and other
than as a result of death or disability) or resignation for good reason, in either case on or within 18 months after the effective date of a
change in control of the Company, and contingent on execution of an effective release of claims against us and satisfaction of certain other
conditions, Dr. Lieu will be entitled to (i) continued payment of his base salary for 6 months; (ii) payment or reimbursement of COBRA
premiums for him and his eligible dependents for up to 6 months; and (iii) full vesting of any unvested equity awards held by Dr. Lieu. The
complete details of the foregoing benefits will be set forth in a written document provided to Dr. Lieu by the Company.

Severance Benefit Addendum

This  Severance  Benefit  Addendum  (“Addendum”),  effective  as  of  December  4,  2023,  to  the  employment  offer  letter  (“Offer  Letter”)  dated
January 16, 2019 by and between Hsiao D. Lieu, M.D. (“Executive”) and NGM Biopharmaceuticals, Inc. (“NGM” or the “Company”) sets forth
the terms of Executive’s severance benefits with the Company. This Addendum forms part of the Offer Letter. Capitalized terms not otherwise
defined herein shall have the meanings ascribed to them in the Offer Letter.

1. Termination Without Cause or Resignation for Good Reason Following a Change in Control. If, on or within eighteen (18) months
after  the  effective  date  of  a  Change  in  Control  (as  defined  herein),  either  (i)  the  Company  terminates  Executive’s  employment  without
Cause  (as  defined  herein)  and  other  than  as  a  result  of  Executive’s  death  or  Disability,  or  (ii)  Executive  resigns  for  Good  Reason  (as
defined herein), and provided in any case (a) such termination or resignation constitutes a “separation from service” (within the meaning
of Treasury Regulation Section 1.409A-l(h)),  (b) Executive signs the Company’s standard form of release within the time period specified
by  the  Company  and  allows  it  to  become  effective  in  accordance  with  its  terms  (but  in  no  event  later  than  sixty  (60)  days  following
Executive’s termination or resignation), and (c) Executive complies with Executive’s obligations under Executive’s Proprietary Information
Agreement, then the Company shall provide Executive with the following severance benefits:

th

1.1 Salary and Benefit Continuation. The Company will pay Executive severance in the form of Base Salary continuation for a six (6)
month  period  following  Executive’s  last  day  of  employment.  These  salary  continuation  payments  will  be  paid  on  the  Company’s
regular  payroll  schedule  and  subject  to  standard  deductions  and  withholdings  over  the  applicable  period  following  termination  or
resignation; provided, however,  that  no  payments  will  be  made  prior  to  the  sixtieth  (60 )  day  following  Executive’s  termination  or
resignation.  On  the  sixtieth  (60 )  day  following  Executive’s  termination  or  resignation  date,  the  Company  will  pay  Executive  in  a
lump sum the salary continuation payments that Executive would have received on or prior to such date under the original schedule
but for the delay while waiting for the release deadline, with the balance of the cash severance being paid as originally scheduled. In
addition,  Executive  shall  have  the  right  to  continue  Executive’s  health  insurance  benefits  pursuant  to  the  Consolidated  Omnibus
Budget Reconciliation Act of 1985 (“COBRA”) or successor statute and any analogous provisions of applicable state law. Provided
that Executive makes a timely and accurate election for continued health insurance coverage (including medical, dental, vision and
prescription) under COBRA (or any state law of similar effect), the Company will pay the premiums for such continued coverage for
Executive and Executive’s eligible dependents for the first six (6) months of such coverage, or such earlier date as Executive (or
Executive’s  dependents,  as  applicable)  ceases  to  be  eligible  for  such  continuation  coverage  (such  payment  period,  the  “COBRA
Payment Period”).

th

Notwithstanding  the  foregoing,  if  at  any  time  the  Company  determines,  in  its  sole  discretion,  that  it  cannot  provide  the  COBRA
premium benefits without potentially incurring financial costs or penalties under applicable law (including, without limitation, Section
2716  of  the  Public  Health  Service  Act),  then  in  lieu  of  paying  COBRA  premiums  directly  to  the  carrier  on  Executive’s  behalf,  the
Company will instead pay Executive on the last day of each remaining month of the COBRA Payment Period a fully taxable cash
payment equal to the value of Executive’s monthly COBRA premium for the first month of COBRA coverage, subject to applicable
tax withholding (such amount, the “Special Severance Payment”), such Special Severance Payment to be made without regard to
Executive’s election of COBRA coverage or payment of COBRA premiums and without regard to Executive’s continued eligibility for
COBRA coverage during the COBRA Payment Period. Such Special Severance Payment shall end upon expiration of the COBRA
Payment Period.

1.2 Accelerated Vesting. The Company will accelerate the vesting of the Stock Rights, to the extent then-outstanding and unvested,
such that all shares subject to the Stock Rights shall be deemed immediately vested and exercisable as of Executive’s termination
or resignation date.

2. Section 409A Compliance. It is intended that each installment of the severance payments and benefits provided for in this Addendum is
a separate “payment” for purposes of Section 409A (“Section 409A”) of the Internal Revenue Code of 1986, as amended (the “Code”).
For  the  avoidance  of  doubt,  it  is  intended  that  the  severance  satisfies,  to  the  greatest  extent  possible,  the  exemptions  from  the
application of Section 409A provided under Treasury Regulation 1.409A-l(b)(4) and 1.409A-l(b)(9). Notwithstanding the foregoing, if the

 
 
 
Company (or, if applicable, the successor entity thereto) determines that the severance payment provided above upon a separation from
service  constitute  “deferred  compensation”  under  Section  409A  and  if  Executive  is  a  “specified  employee”  of  the  Company  or  any
successor entity thereto as of the separation from service, as such term is defined in Section 409A(a)(2)(B)(i) (a “Specified Employee”),
then, solely to the extent necessary to avoid the incurrence of the adverse personal tax consequences under Section 409A, the timing of
the severance (or any portion thereof) shall be delayed as follows: on the earlier to occur of (i) the date that is six (6) months and one (1)
day after the date of separation of service or (ii) the date of Executive’s death (such earlier date, the “Delayed Initial Payment Date”), the
Company  (or  the  successor  entity  thereto,  as  applicable)  shall  (A)  pay  to  Executive  a  lump  sum  amount  equal  to  the  sum  of  the
severance payments that Executive would otherwise have received through the Delayed Initial Payment Date if the commencement of

compensation)  as  in  effect  immediately  prior  to  Executive’s  termination  or  resignation  triggering  benefits  under  this  Addendum,
except  that  base  pay  shall  exclude  any  reduction  that  would  give  rise  to  Executive’s  right  to  a  resignation  for  Good  Reason  (if
applicable).

Dear Valerie,

On behalf of NGM Biopharmaceuticals, Inc. ("NGM" or the "Company"), we are pleased that you will be joining the Company as Senior Vice
President, General Counsel and Chief Compliance Officer reporting to me. We believe this position represents an extraordinary opportunity,
and we look forward to your joining our exceptional team.

Below are details of the compensation and benefits program we are offering as part of your employment with NGM, as well as other terms of
your employment. Should you have questions regarding any part of this offer, or wish to receive additional details, please let us know. Your
annual base salary will be $390,000.00, less payroll deductions and all required withholdings, paid semi- monthly over 24 pay periods per
year. In addition, you will be eligible to participate in the NGM Incentive Bonus Plan. You will also be eligible to receive a one-time sign-on
bonus of $75,000.00, payable within the first two pay periods of your employment with NGM. Should you voluntarily resign from NGM within
two (2) years from your start date, you will be required to repay the pro-rated portion of the sign-on bonus payment based on the number of
months you were employed by the Company following receipt of the sign-on bonus payment. In addition, you will be eligible to receive a one-
time retention bonus of $75,000.00 payable within the first two pay periods following the one-year anniversary of your employment. Should
you voluntarily resign from NGM within two (2) years from the receipt of your retention bonus payment, you will be required to repay the pro-
rated portion of the retention bonus payment based on the number of months you were employed by the Company following receipt of the
retention bonus payment.

NGM provides all eligible employees with a comprehensive benefits program. You will have the opportunity to participate in these benefits,
which include medical, dental and vision coverage for you and your eligible dependents, if you choose to enroll in them. In addition, we
provide life insurance, LTD and AD&D coverage, along with a comprehensive 401(k) program. NGM also provides benefits including
Company holidays, vacation, sick leave and Health Care and Dependent Flexible Spending Accounts. The Company may change
compensation and benefits from time to time in its discretion. There is a formal performance review period once a year.
An important component of your compensation includes the opportunity for ownership in the Company. After you commence employment,
and subject to the approval of our Board of Directors (the "Board"), NGM will grant you an option to purchase 200,000 shares of the
Company's common stock (subject to adjustment for stock splits, stock dividends, reclassification and the like) at the fair market value
determined by the Board as of the date of grant (the "Option"). The Option will be subject to the terms and conditions of the Company's
Equity Incentive Plan (the "Plan") and your grant agreement. Your grant agreement will reflect a four year vesting schedule, under which 25%
of your Option will vest after 12 months and 1/48th of the total will vest at the end of each month thereafter, until either the Option is fully
vested or your employment ends, whichever occurs first.

As a condition of your employment, you will be required to abide by the Company's policies and procedures, including those outlined in our
employee handbook. You also agree to read, sign and comply with the Company's Employee Proprietary Information and Inventions
Agreement ("Proprietary Information Agreement").

In your work for the Company, you will be expected to not make any unauthorized use of, or disclose, the confidential information or
materials, including trade secrets, of any former employer or other third party to whom you owe an obligation of confidentiality. Rather, you
will be expected to use only that information generally known

and used by persons with training and experience comparable to your own, which information is common knowledge in the industry or
otherwise legally available in the public domain, or which is otherwise provided or developed by the Company. By accepting employment with
the Company, you are representing to us that you will be able to perform your duties within the guidelines described in this paragraph. You
represent further that you have disclosed to the Company any contract you have signed that may restrict your activities on behalf of the
Company in any manner.

This offer is contingent upon our verification of your employment history. Any intentional misrepresentation concerning your employment
history may result in actions up to and including revocation of this offer or termination of your employment at NGM.

Your employment relationship is at-will. Accordingly, you may terminate your employment with the Company at any time and for any reason
whatsoever simply by notifying the Company. Likewise, the Company may terminate your employment at any time and for any reason, with
or without cause or advance notice.

Company concerning this offer. The terms of this letter supersede any other representations or agreements made to you by any party,
whether oral or written. The terms of our agreement cannot be changed (except those changes expressly reserved to the Company's
discretion in this letter) other than by a written agreement signed by you and a duly authorized officer of the Company. This agreement is to
be governed by the laws of the state of California without reference to its conflicts of law principles. In case any provision contained in this
agreement shall, for any reason, be held invalid or unenforceable in any respect, such invalidity or unenforceability will not affect the other
provisions of this agreement, and such provision will be construed and enforced so as to render it valid and enforceable consistent with the
general intent of the parties insofar as possible under applicable law. With respect to the enforcement of this agreement, no waiver of any
right hereunder will be effective unless it is in writing. This agreement may be executed in more than one counterpart , and signatures
transmitted electronically will be deemed equivalent to originals. As required by law, this offer is subject to satisfactory proof of your identity
and right to work in the United States.

ADDITIONAL INFORMATION REGARDING SEVERANCE AND CHANGE IN CONTROL ARRANGEMENTS

In addition to the employment offer letter with Ms. Pierce entered into on August 6, 2019, in May 2020 the Compensation Committee

of the NGM Biopharmaceuticals, Inc. Board of Directors determined that, in the event of a termination without cause (and other than as a
result of death or disability) or resignation for good reason, in either case on or within 18 months after the effective date of a change in
control, and contingent on execution of an effective release of claims against us and satisfaction of certain other conditions, Ms. Pierce will
be entitled to (i) continued payment of her base salary for 6 months; (ii) payment or reimbursement of COBRA premiums for her and her
eligible dependents for up to 6 months; and (iii) full vesting of any unvested equity awards held by Ms. Pierce.

Severance Benefit Addendum

This  Severance  Benefit  Addendum  (“Addendum”),  effective  as  of  December  4,  2023,  to  the  employment  offer  letter  (“Offer  Letter”)  dated
August  6,  2019  by  and  between  Valerie  Pierce  (“Executive”)  and  NGM  Biopharmaceuticals,  Inc.  (“NGM”  or  the  “Company”)  sets  forth  the
terms of Executive’s severance benefits with the Company. This Addendum forms part of the Offer Letter. Capitalized terms not otherwise
defined herein shall have the meanings ascribed to them in the Offer Letter.

1. Termination Without Cause or Resignation for Good Reason Following a Change in Control. If, on or within eighteen (18) months
after  the  effective  date  of  a  Change  in  Control  (as  defined  herein),  either  (i)  the  Company  terminates  Executive’s  employment  without
Cause  (as  defined  herein)  and  other  than  as  a  result  of  Executive’s  death  or  Disability,  or  (ii)  Executive  resigns  for  Good  Reason  (as
defined herein), and provided in any case (a) such termination or resignation constitutes a “separation from service” (within the meaning
of Treasury Regulation Section 1.409A-l(h)),  (b) Executive signs the Company’s standard form of release within the time period specified
by  the  Company  and  allows  it  to  become  effective  in  accordance  with  its  terms  (but  in  no  event  later  than  sixty  (60)  days  following
Executive’s termination or resignation), and (c) Executive complies with Executive’s obligations under Executive’s Proprietary Information
Agreement, then the Company shall provide Executive with the following severance benefits:

th

1.1 Salary and Benefit Continuation. The Company will pay Executive severance in the form of Base Salary continuation for a six (6)
month  period  following  Executive’s  last  day  of  employment.  These  salary  continuation  payments  will  be  paid  on  the  Company’s
regular  payroll  schedule  and  subject  to  standard  deductions  and  withholdings  over  the  applicable  period  following  termination  or
resignation; provided, however,  that  no  payments  will  be  made  prior  to  the  sixtieth  (60 )  day  following  Executive’s  termination  or
resignation.  On  the  sixtieth  (60 )  day  following  Executive’s  termination  or  resignation  date,  the  Company  will  pay  Executive  in  a
lump sum the salary continuation payments that Executive would have received on or prior to such date under the original schedule
but for the delay while waiting for the release deadline, with the balance of the cash severance being paid as originally scheduled. In
addition,  Executive  shall  have  the  right  to  continue  Executive’s  health  insurance  benefits  pursuant  to  the  Consolidated  Omnibus
Budget Reconciliation Act of 1985 (“COBRA”) or successor statute and any analogous provisions of applicable state law. Provided
that Executive makes a timely and accurate election for continued health insurance coverage (including medical, dental, vision and
prescription) under COBRA (or any state law of similar effect), the Company will pay the premiums for such continued coverage for
Executive and Executive’s eligible dependents for the first six (6) months of such coverage, or such earlier date as Executive (or
Executive’s  dependents,  as  applicable)  ceases  to  be  eligible  for  such  continuation  coverage  (such  payment  period,  the  “COBRA
Payment Period”).

th

Notwithstanding  the  foregoing,  if  at  any  time  the  Company  determines,  in  its  sole  discretion,  that  it  cannot  provide  the  COBRA
premium benefits without potentially incurring financial costs or penalties under applicable law (including, without limitation, Section
2716  of  the  Public  Health  Service  Act),  then  in  lieu  of  paying  COBRA  premiums  directly  to  the  carrier  on  Executive’s  behalf,  the
Company will instead pay Executive on the last day of each remaining month of the COBRA Payment Period a fully taxable cash
payment equal to the value of Executive’s monthly COBRA premium for the first month of COBRA coverage, subject to applicable
tax withholding (such amount, the “Special Severance Payment”), such Special Severance Payment to be made without regard to
Executive’s election of COBRA coverage or payment of COBRA premiums and without regard to Executive’s continued eligibility for
COBRA coverage during the COBRA Payment Period. Such Special Severance Payment shall end upon expiration of the COBRA
Payment Period.

1.2 Accelerated Vesting. The Company will accelerate the vesting of the Stock Rights, to the extent then-outstanding and unvested,
such that all shares subject to the Stock Rights shall be deemed immediately vested and exercisable as of Executive’s termination
or resignation date.

2. Section 409A Compliance. It is intended that each installment of the severance payments and benefits provided for in this Addendum is
a separate “payment” for purposes of Section 409A (“Section 409A”) of the Internal Revenue Code of 1986, as amended (the “Code”).
For  the  avoidance  of  doubt,  it  is  intended  that  the  severance  satisfies,  to  the  greatest  extent  possible,  the  exemptions  from  the
application of Section 409A

 
 
 
provided under Treasury Regulation 1.409A-l(b)(4) and 1.409A-l(b)(9). Notwithstanding the foregoing, if the Company (or, if applicable,
the successor entity thereto) determines that the severance payment provided above upon a separation from service constitute “deferred
compensation” under Section 409A and if Executive is a “specified employee” of the Company or any successor entity thereto as of the
separation  from  service,  as  such  term  is  defined  in  Section  409A(a)(2)(B)(i)  (a  “Specified  Employee”),  then,  solely  to  the  extent
necessary to avoid the incurrence of the adverse personal tax consequences under Section 409A, the timing of the severance (or any
portion thereof) shall be delayed as follows: on the earlier to occur of (i) the date that is six (6) months and one (1) day after the date of
separation of service or (ii) the date of Executive’s death (such earlier date, the “Delayed Initial Payment Date”), the Company (or the
successor entity thereto, as applicable) shall (A) pay to Executive a lump sum amount equal to the sum of the severance payments that
Executive  would  otherwise  have  received  through  the  Delayed  Initial  Payment  Date  if  the  commencement  of  the  payment  of  the
severance had not been delayed pursuant to this paragraph and (B) commence paying the balance of the severance in accordance with
the payment schedule set forth above.

3. Definitions. For purposes of this Addendum, the following terms used herein have the definitions set forth below.

3.1 “Base Salary” means base pay (excluding incentive pay, premium pay, commissions, overtime, bonuses and other forms of variable
compensation)  as  in  effect  immediately  prior  to  Executive’s  termination  or  resignation  triggering  benefits  under  this  Addendum,
except  that  base  pay  shall  exclude  any  reduction  that  would  give  rise  to  Executive’s  right  to  a  resignation  for  Good  Reason  (if
applicable).

3.2 “Cause” has the meaning ascribed to such term in the Plan.
3.3 “Change in Control” has the meaning ascribed to such term in the Plan.
3.4 “Disability” has the meaning ascribed to such term in the Plan.
3.5 “Good  Reason”  means:  if  any  of  the  following  actions  are  taken  by  the  Company  or  a  successor  corporation  or  entity  without
Executive’s consent, provided that Executive notifies the Company (or successor, as applicable) in writing, within ten (10) days after
the occurrence of one of the following actions, that Executive intends to terminate Executive’s employment no earlier than thirty (30)
days  after  providing  such  notice,  and  the  Company  (or  successor,  as  applicable)  fails  to  cure  such  actions  within  thirty  (30)  days
after  receipt  of  such  notice,  and  Executive’s  resignation  is  effective  not  later  than  (30)  days  after  the  Company  (or  successor,  as
applicable)  fails  to  cure  the  issue:  (a)  a  substantial  reduction  of  Executive’s  base  salary;  (b)  a  material  reduction  in  Executive’s
duties; (c) a material breach by the Company (or a successor corporation or entity, if applicable) of any provision of the Offer Letter,
including this Addendum; or (d) a relocation of Executive’s principal place of employment to a place that increases Executive’s one-
way commute by greater than fifty (50) miles as compared to Executive’s then-current principal place of employment prior to such
relocation (excluding regular travel in the ordinary course of business); provided that (i) if Executive’s principal place of employment
is  Executive’s  personal  residence,  this  clause  (d)  shall  not  apply  and  (ii)  if  Executive  works  remotely  during  any  period  in  which
Executive’s regular principal office location is a Company office that is closed, then neither Executive’s relocation to remote work or
back  to  the  office  from  remote  work  will  be  considered  a  relocation  of  Executive’s  principal  office  location  for  purposes  of  this
definition.

3.6 “Plan” means the Company’s Amended and Restated 2018 Equity Incentive Plan, as amended from time to time, or any successor

plan thereto.

3.7 “Stock Rights”  means  all  of  Executive’s  options,  restricted  stock,  restricted  stock  units  or  rights  to  acquire  vested  ownership  of
shares  of  the  Company’s  Common  Stock  under  plans,  agreements  or  arrangements  that  are  compensatory  in  nature,  including,
without limitation, the Option, the Plan and other agreements between the Company and Executive.

IN WITNESS WHEREOF, the parties hereto have executed this Addendum on and as of the day and year first above written.

terminaon  of  your  employment,  shall  be  resolved  pursuant  to  the  Federal  Arbitraon  Act,  9  U.S.C.  §  1-16,  to  the  fullest  extent
permied by law, by final, binding and confidenal arbitraon conducted by JAMS, Inc. (“JAMS”) or its successor, under such arbitraon
service’s then applicable rules and procedures appropriate to the relief being sought (available upon request and also currently available
at the following web address(es):

(ii)

hps://www.jamsadr.com/rules-comprehensive-arbitraon/)

at  a  locaon  closest  to  where  you  last  worked  for  the  Company  or  another  mutually  agreeable  locaon.  You  acknowledge  that  by
agreeing to this arbitraon procedure, both you and the Company waive the right to resolve any such dispute through a trial by jury
or judge.

This arbitraon agreement shall not be mandatory for any claim or cause of acon to the extent applicable law prohibits subjecng such
claim or cause of acon to mandatory arbitraon and such applicable law is not preempted by the Federal Arbitraon Act or otherwise
invalid (collecvely, the “Excluded Claims”), including claims or causes of acon alleging sexual harassment or a nonconsensual sexual
act or sexual contact, or unemployment or workers’ compensaon claims brought before the applicable state governmental agency. In
the event you or the Company intend to bring mulple claims, including one of the Excluded Claims listed above, the Excluded Claims
may be filed with a court, while any other claims will remain subject to mandatory arbitraon. Nothing herein prevents you from filing
and  pursuing  proceedings  before  a  federal  or  state  governmental  agency,  although  if  you  choose  to  pursue  a  claim  following  the
exhauson of any applicable administrave remedies, that claim would be subject to this provision. In addion, with the excepon of
Excluded  Claims  arising  out  of  9  U.S.C.,  chapter  4,  all  claims,  disputes,  or  causes  of  acon  under  this  secon,  whether  by  you  or  the
Company,  must  be  brought  in  an  individual  capacity,  and  shall  not  be  brought  as  a  plainff  (or  claimant)  or  class  member  in  any
purported class or representave proceeding, nor joined or consolidated with the claims of any other person or enty. The arbitrator
may  not  consolidate  the  claims  of  more  than  one  person  or  enty  and  may  not  preside  over  any  form  of  representave  or  class
proceeding.  To  the  extent  that  the  preceding  sentences  regarding  class  or  representave  claims  or  proceedings  are  found  to  violate
applicable law or are otherwise found unenforceable, any claim(s) alleged or brought on behalf of a class or in a representave capacity
shall proceed in a court of law rather than by arbitraon.

You  will  have  the  right  to  be  represented  by  legal  counsel  at  any  arbitraon  proceeding.  Quesons  of  whether  a  claim  is  subject  to
arbitraon under this arbitraon agreement shall be decided by the arbitrator. Likewise,

procedural quesons which grow out of the dispute and bear on the final disposion are also maers for the arbitrator. Notwithstanding
the foregoing, provided however, that if required by applicable law, a court and not the arbitrator may determine the enforceability of
the previous secon with respect to Excluded Claims. The arbitrator shall: (a) have the authority to compel adequate discovery for the
resoluon of the dispute and to award such relief as would otherwise be permied by law; and (b) issue a wrien statement signed by
the arbitrator regarding the disposion of each claim and the relief, if any, awarded as to each claim, the reasons for the award, and the
arbitrator’s essenal findings and conclusions on which the award is based. The arbitrator shall be authorized to award all relief that you
or the Company would be entled to seek in a court of law.

For California and Hawaii Employees Only: The Company shall pay all arbitraon administrave fees in excess of the administrave fees
that you would be required to pay if the dispute were decided in a court of law. Each party is responsible for its own aorneys’ fees,
except as may be expressly set forth in your employee confidenal informaon and invenons assignment agreement or as otherwise
provided under applicable law. Nothing in this arbitraon agreement is intended to prevent either you or the Company from obtaining
injuncve  relief  in  court  to  prevent  irreparable  harm  pending  the  conclusion  of  any  such  arbitraon.  Any  awards  or  orders  in  such
arbitraons may be entered and enforced as judgments in the federal and state courts of any competent jurisdicon.

This arbitraon agreement will be effecve as of my first day of employment with the Company.

Severance Benefit Addendum

This  Severance  Benefit  Addendum  (“Addendum”),  effective  as  of  December  4,  2023,  to  the  employment  offer  letter  (“Offer  Letter”)  dated
October  18,  2023  by  and  between  Jean-Frederic  Viret,  Ph.D.  (“Executive”)  and  NGM  Biopharmaceuticals,  Inc.  (“NGM”  or  the  “Company”)
sets forth the terms of Executive’s severance benefits with the Company. This Addendum forms part of the Offer Letter. Capitalized terms not
otherwise defined herein shall have the meanings ascribed to them in the Offer Letter.

1. Termination Without Cause or Resignation for Good Reason Following a Change in Control. If, on or within eighteen (18) months
after  the  effective  date  of  a  Change  in  Control  (as  defined  herein),  either  (i)  the  Company  terminates  Executive’s  employment  without
Cause  (as  defined  herein)  and  other  than  as  a  result  of  Executive’s  death  or  Disability,  or  (ii)  Executive  resigns  for  Good  Reason  (as
defined herein), and provided in any case (a) such termination or resignation constitutes a “separation from service” (within the meaning
of Treasury Regulation Section 1.409A-l(h)),  (b) Executive signs the Company’s standard form of release within the time period specified
by  the  Company  and  allows  it  to  become  effective  in  accordance  with  its  terms  (but  in  no  event  later  than  sixty  (60)  days  following
Executive’s termination or resignation), and (c) Executive complies with Executive’s obligations under Executive’s Proprietary Information
Agreement, then the Company shall provide Executive with the following severance benefits:

th

1.1 Salary and Benefit Continuation. The Company will pay Executive severance in the form of Base Salary continuation for a six (6)
month  period  following  Executive’s  last  day  of  employment.  These  salary  continuation  payments  will  be  paid  on  the  Company’s
regular  payroll  schedule  and  subject  to  standard  deductions  and  withholdings  over  the  applicable  period  following  termination  or
resignation; provided, however,  that  no  payments  will  be  made  prior  to  the  sixtieth  (60 )  day  following  Executive’s  termination  or
resignation.  On  the  sixtieth  (60 )  day  following  Executive’s  termination  or  resignation  date,  the  Company  will  pay  Executive  in  a
lump sum the salary continuation payments that Executive would have received on or prior to such date under the original schedule
but for the delay while waiting for the release deadline, with the balance of the cash severance being paid as originally scheduled. In
addition,  Executive  shall  have  the  right  to  continue  Executive’s  health  insurance  benefits  pursuant  to  the  Consolidated  Omnibus
Budget Reconciliation Act of 1985 (“COBRA”) or successor statute and any analogous provisions of applicable state law. Provided
that Executive makes a timely and accurate election for continued health insurance coverage (including medical, dental, vision and
prescription) under COBRA (or any state law of similar effect), the Company will pay the premiums for such continued coverage for
Executive and Executive’s eligible dependents for the first six (6) months of such coverage, or such earlier date as Executive (or
Executive’s  dependents,  as  applicable)  ceases  to  be  eligible  for  such  continuation  coverage  (such  payment  period,  the  “COBRA
Payment Period”).

th

Notwithstanding  the  foregoing,  if  at  any  time  the  Company  determines,  in  its  sole  discretion,  that  it  cannot  provide  the  COBRA
premium benefits without potentially incurring financial costs or penalties under applicable law (including, without limitation, Section
2716  of  the  Public  Health  Service  Act),  then  in  lieu  of  paying  COBRA  premiums  directly  to  the  carrier  on  Executive’s  behalf,  the
Company will instead pay Executive on the last day of each remaining month of the COBRA Payment Period a fully taxable cash
payment equal to the value of Executive’s monthly COBRA premium for the first month of COBRA coverage, subject to applicable
tax withholding (such amount, the “Special Severance Payment”), such Special Severance Payment to be made without regard to
Executive’s election of COBRA coverage or payment of COBRA premiums and without regard to Executive’s continued eligibility for
COBRA coverage during the COBRA Payment Period. Such Special Severance Payment shall end upon expiration of the COBRA
Payment Period.

1.2 Accelerated Vesting. The Company will accelerate the vesting of the Stock Rights, to the extent then-outstanding and unvested,
such that all shares subject to the Stock Rights shall be deemed immediately vested and exercisable as of Executive’s termination
or resignation date.

 
 
 
2. Section 409A Compliance. It is intended that each installment of the severance payments and benefits provided for in this Addendum is
a separate “payment” for purposes of Section 409A (“Section 409A”) of the Internal Revenue Code of 1986, as amended (the “Code”).
For  the  avoidance  of  doubt,  it  is  intended  that  the  severance  satisfies,  to  the  greatest  extent  possible,  the  exemptions  from  the
application of Section 409A provided under Treasury Regulation 1.409A-l(b)(4) and 1.409A-l(b)(9). Notwithstanding the foregoing, if the
Company (or, if applicable, the successor entity thereto) determines that the severance payment provided above upon a separation from
service  constitute  “deferred  compensation”  under  Section  409A  and  if  Executive  is  a  “specified  employee”  of  the  Company  or  any
successor entity thereto as of the separation from service, as such term is defined in Section 409A(a)(2)(B)(i) (a “Specified Employee”),
then, solely to the extent necessary to avoid the incurrence of the adverse personal tax consequences under Section 409A, the timing of
the severance (or any portion thereof) shall be delayed as follows: on the earlier to occur of (i) the date that is six (6) months and one (1)
day after the date of separation of service or (ii) the date of Executive’s death (such earlier date, the “Delayed Initial Payment Date”), the
Company  (or  the  successor  entity  thereto,  as  applicable)  shall  (A)  pay  to  Executive  a  lump  sum  amount  equal  to  the  sum  of  the
severance payments that Executive would otherwise have received through the Delayed Initial Payment Date if the commencement of
the payment of the severance had not been delayed pursuant to this paragraph and (B) commence paying the balance of the severance
in accordance with the payment schedule set forth above.

3. Definitions. For purposes of this Addendum, the following terms used herein have the definitions set forth below.

3.1 “Base Salary” means base pay (excluding incentive pay, premium pay, commissions, overtime, bonuses and other forms of variable
compensation)  as  in  effect  immediately  prior  to  Executive’s  termination  or  resignation  triggering  benefits  under  this  Addendum,
except  that  base  pay  shall  exclude  any  reduction  that  would  give  rise  to  Executive’s  right  to  a  resignation  for  Good  Reason  (if
applicable).

3.2 “Cause” has the meaning ascribed to such term in the Plan.
3.3 “Change in Control” has the meaning ascribed to such term in the Plan.
3.4 “Disability” has the meaning ascribed to such term in the Plan.
3.5 “Good  Reason”  means:  if  any  of  the  following  actions  are  taken  by  the  Company  or  a  successor  corporation  or  entity  without
Executive’s consent, provided that Executive notifies the Company (or successor, as applicable) in writing, within ten (10) days after
the occurrence of one of the following actions, that Executive intends to terminate Executive’s employment no earlier than thirty (30)
days  after  providing  such  notice,  and  the  Company  (or  successor,  as  applicable)  fails  to  cure  such  actions  within  thirty  (30)  days
after  receipt  of  such  notice,  and  Executive’s  resignation  is  effective  not  later  than  (30)  days  after  the  Company  (or  successor,  as
applicable)  fails  to  cure  the  issue:  (a)  a  substantial  reduction  of  Executive’s  base  salary;  (b)  a  material  reduction  in  Executive’s
duties; (c) a material breach by the Company (or a successor corporation or entity, if applicable) of any provision of the Offer Letter,
including this Addendum; or (d) a relocation of Executive’s principal place of employment to a place that increases Executive’s one-
way commute by greater than fifty (50) miles as compared to Executive’s then-current principal place of employment prior to such
relocation (excluding regular travel in the ordinary course of business); provided that (i) if Executive’s principal place of employment
is  Executive’s  personal  residence,  this  clause  (d)  shall  not  apply  and  (ii)  if  Executive  works  remotely  during  any  period  in  which
Executive’s regular principal office location is a Company office that is closed, then neither Executive’s relocation to remote work or
back  to  the  office  from  remote  work  will  be  considered  a  relocation  of  Executive’s  principal  office  location  for  purposes  of  this
definition.

3.6 “Plan” means the Company’s Amended and Restated 2018 Equity Incentive Plan, as amended from time to time, or any successor

plan thereto.

3.7 “Stock Rights”  means  all  of  Executive’s  options,  restricted  stock,  restricted  stock  units  or  rights  to  acquire  vested  ownership  of
shares  of  the  Company’s  Common  Stock  under  plans,  agreements  or  arrangements  that  are  compensatory  in  nature,  including,
without limitation, the Option, the Plan and other agreements between the Company and Executive.

IN WITNESS WHEREOF, the parties hereto have executed this Addendum on and as of the day and year first above written.

Exhibit 97.1

INCENTIVE COMPENSATION RECOUPMENT POLICY

The Board of Directors (the “Board”) of NGM Biopharmaceuticals, Inc., a Delaware corporation (the “Company”), has
determined  that  it  is  in  the  best  interests  of  the  Company  and  its  stockholders  to  adopt  this  Incentive  Compensation
Recoupment Policy (this “Policy”) providing for the Company’s recoupment of Recoverable Incentive Compensation (as defined
below) that is received by Covered Officers (as defined below) of the Company under certain circumstances.

This Policy is designed to comply with, and shall be interpreted to be consistent with, Section 10D of the U.S. Securities
Exchange  Act  of  1934,  as  amended  (the  “Exchange Act”),  Rule  10D-1  promulgated  thereunder  (“Rule  10D-1”)  and  Nasdaq

issued financial statements, or that would result in a material misstatement if the error were corrected in the current period or left
uncorrected in the current period.

“Accounting  Restatement  Date”  means  the  earlier  to  occur  of  (a)  the  date  that  the  Board,  a  committee  of  the  Board
authorized  to  take  such  action,  or  the  officer  or  officers  of  the  Company  authorized  to  take  such  action  if  Board  action  is  not

Company’s financial statements or included in a filing with the SEC in order to be a Financial Reporting Measure.

“Incentive Compensation” means any compensation that is granted, earned or vested based wholly or in part upon the
attainment  of  a  Financial  Reporting  Measure.  For  clarity,  Incentive  Compensation  does  not  include  base  salaries,  bonuses  or
equity  awards  paid  solely  upon  satisfying  one  or  more  subjective  standards,  strategic  or  operational  measures,  or  continued
employment, unless such base salaries, bonuses, or equity awards were granted, paid, or vested (as applicable) based in part
on a Financial Reporting Measure.

“Lookback Period”  means  the  three  completed  fiscal  years  immediately  preceding  the  Accounting  Restatement  Date,
as  well  as  any  transition  period  (resulting  from  a  change  in  the  Company’s  fiscal  year)  within  or  immediately  following  those
three  completed  fiscal  years  (except  that  a  transition  period  of  at  least  nine  months  shall  count  as  a  completed  fiscal  year).
Notwithstanding the foregoing, the Lookback Period shall not include fiscal years completed prior to the Effective Date.

“Recoverable  Incentive  Compensation”  means  Incentive  Compensation  received  by  a  Covered  Officer  during  the
Lookback Period that exceeds the amount of Incentive Compensation that would have been received had such amount been
determined  based  on  the  Accounting  Restatement,  computed  without  regard  to  any  taxes  paid  (i.e., on a gross basis without
regarding to tax withholdings and other deductions). For any compensation plans or programs that take into account Incentive
Compensation, the amount of Recoverable Incentive Compensation for purposes of this Policy shall include, without limitation,
the amount contributed to any notional account based on Recoverable Incentive Compensation and any earnings to date on that
notional  amount.  For  any  Incentive  Compensation  that  is  based  on  stock  price  or  TSR,  where  the  Recoverable  Incentive
Compensation  is  not  subject  to  mathematical  recalculation  directly  from  the  information  in  an  Accounting  Restatement,  the
Administrator will determine the amount of Recoverable Incentive Compensation based on a reasonable estimate of the effect of
the Accounting Restatement on the stock price or TSR upon which the Incentive Compensation was received. The Company
shall maintain documentation of the determination of that reasonable estimate and provide such documentation to the Exchange
in accordance with the Listing Standards.

“SEC” means the U.S. Securities and Exchange Commission.

Effective Date

This Policy shall apply to all Incentive Compensation that is received by a Covered Officer on or after October 2, 2023
(the  “Effective  Date”).  Incentive  Compensation  is  deemed  “received”  in  the  Company’s  fiscal  period  in  which  the  Financial
Reporting Measure specified in the Incentive Compensation award is attained, even if the payment or grant of such Incentive
Compensation occurs after the end of that period.

Recoupment

Applicability of Policy

This  Policy  applies  to  Incentive  Compensation  received  by  a  Covered  Officer  (a)  after  beginning  services  as  an
Executive  Officer,  (b)  who  served  as  an  Executive  Officer  at  any  time  during  the  performance  period  for  such  Incentive
Compensation, (c) while the Company had a class of securities listed on a national securities exchange or a national securities
association, and (d) during the Lookback Period.

Recoupment Generally

Pursuant to the provisions of this Policy, if there is an Accounting Restatement, the Company must reasonably promptly
recoup  the  full  amount  of  the  Recoverable  Incentive  Compensation,  unless  the  conditions  of  one  or  more  subsections  of  the
section of this Policy entitled “Impracticability of Recovery” are met and the Compensation Committee, or, if such committee
does  not  consist  solely  of  independent  directors,  a  majority  of  the  independent  directors  serving  on  the  Board,  has  made  a
determination  that  recoupment  would  be  impracticable.  Recoupment  is  required  regardless  of  whether  the  Covered  Officer
engaged  in  any  misconduct  and  regardless  of  fault,  and  the  Company’s  obligation  to  recoup  Recoverable  Incentive
Compensation is not dependent on whether or when any restated financial statements are filed.

Impracticability of Recovery

Recoupment may be determined to be impracticable if, and only if:

(a)

the  direct  expense  paid  to  a  third  party  to  assist  in  enforcing  this  Policy  would  exceed  the  amount  of  the
applicable Recoverable Incentive Compensation; provided that, before concluding that it would be impracticable to recover any
amount  of  Recoverable  Incentive  Compensation  based  on  expense  of  enforcement,  the  Company  shall  make  a  reasonable
attempt  to  recover  such  Recoverable  Incentive  Compensation,  document  such  reasonable  attempt(s)  to  recover,  and  provide
that documentation to the Exchange in accordance with the Listing Standards; or

(b)

recoupment of the applicable Recoverable Incentive Compensation would likely cause an otherwise tax-qualified
retirement  plan,  under  which  benefits  are  broadly  available  to  employees  of  the  Company,  to  fail  to  meet  the  requirements  of
Code Section 401(a)(13) or Code Section 411(a) and regulations thereunder.

Sources of Recoupment

To the extent permitted by applicable law, the Administrator shall, in its sole discretion, determine the timing and method
for  recouping  Recoverable  Incentive  Compensation  hereunder,  provided  that  such  recoupment  is  undertaken  reasonably
promptly. The Administrator may, in its discretion, seek recoupment from a Covered Officer from any of the following sources or
a combination thereof, whether the applicable compensation was approved, awarded, granted, payable or paid to the Covered
Officer prior to, on or after the Effective Date: (a) direct repayment of Recoverable Incentive Compensation previously paid to
the Covered Officer; (b) cancelling prior cash or equity-based awards (whether vested or unvested and whether paid or unpaid);
(c)  cancelling  or  offsetting  against  any  planned  future  cash  or  equity-based  awards;  (d)  forfeiture  of  deferred  compensation,
subject to compliance with Code Section 409A; and (e) any other method authorized by applicable law or contract. Subject to
compliance with any applicable law, the

3

Administrator may effectuate recoupment under this Policy from any amount otherwise payable to the Covered Officer, including
amounts  payable  to  such  individual  under  any  otherwise  applicable  Company  plan  or  program,  e.g.,  base  salary,  bonuses  or
commissions and compensation previously deferred by the Covered Officer. The Administrator need not utilize the same method
of recovery for all Covered Officers or with respect to all types of Recoverable Incentive Compensation.

No Indemnification of Covered Officers

Notwithstanding any indemnification agreement, applicable insurance policy or any other agreement or provision of the
Company’s  certificate  of  incorporation  or  bylaws  to  the  contrary,  no  Covered  Officer  shall  be  entitled  to  indemnification  or
advancement of expenses in connection with any enforcement of this Policy by the Company, including paying or reimbursing
such Covered Officer for insurance premiums to cover potential obligations to the Company under this Policy.

Indemnification of Administrator

Any members of the Administrator, and any other members of the Board who assist in the administration of this Policy,
shall  not  be  personally  liable  for  any  action,  determination  or  interpretation  made  with  respect  to  this  Policy  and  shall  be
indemnified  by  the  Company  to  the  fullest  extent  under  applicable  law  and  Company  policy  with  respect  to  any  such  action,
determination or interpretation. The foregoing sentence shall not limit any other rights to indemnification of the members of the
Board under applicable law or Company policy.

No “Good Reason” for Covered Officers

Any action by the Company to recoup or any recoupment of Recoverable Incentive Compensation under this Policy from
a  Covered  Officer  shall  not  be  deemed  (a)  “good  reason”  for  resignation  or  to  serve  as  a  basis  for  a  claim  of  constructive
termination under any benefits or compensation arrangement applicable to such Covered Officer, or (b) to constitute a breach of
a contract or other arrangement to which such Covered Officer is party.

Administration of Policy

Except  as  specifically  set  forth  herein,  this  Policy  shall  be  administered  by  the  Administrator.  The  Administrator  shall
have  full  and  final  authority  to  make  any  and  all  determinations  required  under  this  Policy.  Any  determination  by  the
Administrator with respect to this Policy shall be final, conclusive and binding on all interested parties and need not be uniform
with  respect  to  each  individual  covered  by  this  Policy.  In  carrying  out  the  administration  of  this  Policy,  the  Administrator  is
authorized and directed to consult with the full Board or such other committees of the Board as may be necessary or appropriate
as to matters within the scope of such other committee’s responsibility and authority. Subject to applicable law, the Administrator
may authorize and empower any officer or employee of the Company to take any and all actions that the Administrator, in its
sole discretion, deems necessary or appropriate to carry out the purpose and intent of this Policy (other than with respect to any
recovery under this Policy involving such officer or employee).

4

Severability

If  any  provision  of  this  Policy  or  the  application  of  any  such  provision  to  a  Covered  Officer  shall  be  adjudicated  to  be
invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provisions of
this Policy, and the invalid, illegal or unenforceable provisions shall be deemed amended to the minimum extent necessary to
render any such provision or application enforceable.

No Impairment of Other Remedies

Nothing contained in this Policy, and no recoupment or recovery as contemplated herein, shall limit any claims, damages
or other legal remedies the Company or any of its affiliates may have against a Covered Officer arising out of or resulting from
any actions or omissions by the Covered Officer. This Policy does not preclude the Company from taking any other action to
enforce  a  Covered  Officer’s  obligations  to  the  Company,  including,  without  limitation,  termination  of  employment  and/or
institution of civil proceedings. This Policy is in addition to the requirements of Section 304 of the Sarbanes-Oxley Act of 2002
(“SOX  304”)  that  are  applicable  to  the  Company’s  Chief  Executive  Officer  and  Chief  Financial  Officer  and  to  any  other
compensation  recoupment  policy  and/or  similar  provisions  in  any  employment,  equity  plan,  equity  award  or  other  individual
agreement to which the Company is a party or which the Company has adopted or may adopt and maintain from time to time;
provided,  however,  that  compensation  recouped  pursuant  to  this  Policy  shall  not  be  duplicative  of  compensation  recouped
pursuant  to  SOX  304  or  any  such  compensation  recoupment  policy  and/or  similar  provisions  in  any  such  employment,  equity
plan, equity award or other individual agreement except as may be required by law.

Amendment; Termination

The Administrator may amend, terminate or replace this Policy or any portion of this Policy at any time and from time to
time in its sole discretion. The Administrator shall amend this Policy as it deems necessary to comply with applicable law or any
Listing Standard.

Successors

This  Policy  shall  be  binding  and  enforceable  against  all  Covered  Officers  and,  to  the  extent  required  by  Rule  10D-1

and/or the applicable Listing Standards, their beneficiaries, heirs, executors, administrators or other legal representatives.

Required Filings

The Company shall make any disclosures and filings with respect to this Policy that are required by law, including as

required by the SEC.

Adopted by the Company’s Board of Directors on November 8, 2023
